At the start of each co-op game, you must make a selection to pick a character and in addition to character, a co-op role. The role determines what your game plan will be for the incoming game. Each character will have a role rating for A through E for each role, the higher the letter grade, the less points provided for deck construction. A ranks are not always guarantees that something is good, and E ranks are not always indicators of things you should never do with a character. There are lots of tricks in co-op where you have to spend time and see what some characters are still capable of.

With any role you will want to reach level 10 ASAP so that you unlock all of the card points for the role possible and to unlock the role hyper and role ability that comes with each role. Playing single player games with fast forward will provide quick role xp, but you won't gain any xp like you would playing online. You can try single player games or spectate co-op games to see how roles work if you have no co-op experience before jumping into online games yourself. It is recommended to avoid Hyper difficulty bosses until you get to level 10 in a role as you won't have all your options unlocked for a role until level 10.





Attacker: The main source of damage for the team in most games. Attackers are important against most bosses and every team will typically want at least one Attacker or a situation could arise where there's no chance for survival if the game goes on too long. Characters that do not have negative ATK and typically a hyper that will help to boost damage or chances of fighting enemies are ideal for this role. Picking Attacker automatically adds +1 to REC, which is an issue if multiple people pick this role. Don’t put all of your chips into this role so you aren’t a one trick Attacker player.

Attackers are able to attack the boss first regardless of who engages a challenge. Sometimes an Attacker may want to stop in front of a boss instead of always fighting directly to avoid an incoming boss card or to block the boss' movement for a nearby teammate in front of the Attacker since the boss normally stops upon attacking the first player it meets. Always check the board, teammate placements, cards the boss is about to play and any other mobs before going for a direct challenge with a boss. Attacker is generally the most straight-forward role, but there are times smart plays can still be made where you can protect a teammate from getting attacked, so always be paying attention to where everything is on the board.

At level 10, role hyper Ultimate Weapon in the Sun is unlocked, you can switch out your character hyper for the role hyper during deck building. The role hyper adds +3 damage to your attacks in your next battle but they must hit. Its cost was lowered in the Pool Party update so it is a more considerable pick now. At level 5, Fury is unlocked as the role ability, which is only usable in a battle but adds +1 to damage if an attack lands. It is useful as extra damage against a boss or to KO a pesky mob enemy that needs to die such as a Haruo Chicken.

2: +1 ATK
4: +1 ATK





Guardian: Guardian, often referred to as Defender, was one of the lesser roles in co-op but blessed with radical changes in the Pool Party update. They are a huge help against some bosses such as Jonathan or Summer Beast who have many cards that deal damage or spawn plenty of mobs, but also more notably the new boss Swimming Coach. The main objective of a Guardian is to give shields to teammates which will nullify 2 damage from the next hit a receiver takes. If the receiver net defend roll is equal to or higher to an attack received in battle, damage will become 0. The shield will now remain on the receiver until they take any type of damage, a nice buff from the shield of older days.

Guardians can only have 1 active shield out at a time and instead of costing 1 HP to give to a teammate now have a cooldown during the turn after use, so Guardians have to be mindful and decide whether or not anyone is in enough danger to warrant using a shield or to hold on to their stock for something bigger later on. Shields will be color-coordinated based on the Guardian's player slot (i.e. Player 1 Red, Player 2 Blue etc.) so that there is no possible confusion in games two or more Guardians play in at the same time.

Guardians are not expected to be dealing big damage all the time, but a character with a good hyper can still contribute at times and could be helpful. Due to Guardian being a backseat role not focused on doing big damage but keeping the team alive, role hyper might be picked more often with this role to provide the team more stacks of damage nullification to slow down the team from getting KO'd.

Guardians now start with an ability with a 4 turn cooldown called Iron usable in battle. If your DEF roll equals or beats an incoming ATK, you take no damage. Note that Iron does not stack with any spirit defense, so using it when you have any spirit defense active would be a waste. Reaching level 10 will unlock the role hyper Lifeguard on the White Beach, which provides 2 spirit defense to the team in each character's next battle. Damage is nullified completely if DEF roll + spirit beats or equals an ATK roll. Reaching level 5 will unlock the Spirit role ability, which gives a +1 spirit defense to your team over 2 turns.

Norma Buffs:
2: +1 DEF
4: +1 DEF





Support: Supports, sometimes referred to as Healers, are often a secondary requirement to a solid team foundation. Similarly to Guardians, Supports will not always be expected to be going for lots of battles and being a big source of damage for the team as their main role is to stay alive, heal, revive, and support their team any way they possibly can with various cards or hypers. They are still able to sometimes help out in a pinch depending on their hyper, but staying alive is a priority for a Support character compared to much else except KO'ing a weakened enemy.

Any character with a positive EVD value or low REC is a good candidate for a Support character due to how Norma buffs work. Extra movement will help you catch teammates to heal them or to revive them which costs (their current REC value x 3 stars). Do what you can to avoid confrontation as much as possible and don't go for any giant risks where avoidable unless there is a good chance i.e. KO'ing a weakened mob monster with a direct attack.

Since reviving a teammate can be a powerful game-saving ability, hyper choice between character hyper or role hyper can be a toss up. This choice will vary wildly by character so it is up to you to decide based on the team you see being built during deck construction.

At level 10, Guardian of Blooming Flowers role hyper will unlock, which will revive a KO'd ally to full health. At level 5, Restore will be unlocked as a role ability which revives a fallen teammate with 50% HP rounded up. This is typically important to revive an Attacker that has been KO'd and stuck due to high REC values or anyone else to prevent the whole team from being KO'd and losing the game. Always try your best to revive someone in a way that they won't be dying immediately afterward.

3: +1 EVD
4: +1 MOV

Avenger: Avenger role is unlocked after reaching Attacker level 10 or previously as a global counter reward during the 2018 Beach Party event. Avengers thrive in taking a huge punch from an enemy and retaliating with a huge attack buff relative to damage taken for the battle. For every HP lost in a battle, the Avenger gains +1 ATK extra while the battle is active. Due to this passive, Avengers have to play differently than attackers as they need to attack 2nd to get the benefit of their revenge attacks. Attacking first never lets an Avenger use this special revenge attack capability they have. As a result, Avengers usually want to land on boss panels as their main attack source or to land in front of an enemy expecting an attack shortly after once they move into the player.

The typical character that should be picked with this role should usually have at least 5 HP and neutral ATK value, anything under these values and the value of picking Avenger begins to be lost unless there is some special gimmick they have to warrant use under this role such as Noble Fernet. Negative evade values are also a better trait to have for the role so that a player can purposely fail evading a large attack roll and convert their HP into a big counterattack. After norma buffs, Avengers will have a +2 Max HP bonus and a -1 REC bonus, which helps characters live a little longer and get back in the game sooner after a KO.

At level 10, role hyper Unforgiving Avenger is unlocked, which will bring back the user to full HP if KO'd in battle within 3 turns of the hyper activation. This is HUGE especially for high HP characters like Kiriko or Flying Castle. Beyond is Avenger's role ability that brings a user KO'd in battle back to 3 HP but only if it occurs within 2 chapters after activation. Beyond has been changed to be available as soon as Avenger is unlocked as it is a huge part of Avenger's game plan for 100% guaranteed counterattacks after surviving any attack an enemy may have thrown in battle so don't let it go to waste.

Norma Buffs:
2: +1 HP
3: -1 REC
4: +1 HP





Dealer: Dealer is unlocked after reaching Support Level 10 or previously through a global counter reward in the 2019 Summer Games event. Dealers can give cards to teammates via their Deal ability, but was changed majorly in the Pool Party update. It used to be that a Dealer needed 2 cards minimum in their hand and a random card would go to a not-KO'd player of their choosing. The new effect however is that a Dealer now needs 3 cards to use Deal but can choose ANY player (KO'd or not) and can choose the specific card that is dealt out. Characters to play for Dealer will vary, as some have hypers that can be tremendous support for their teammates (i.e. Ellie, Suguri, Halena hypers) and others usually have no major benefit to passing hypers (i.e. Natsumi, Fernet, Star Breaker hypers) and in these cases would be picked as a means of doubling down on trying to obtain copies of said hypers faster. The impact the Dealer has on damaging enemies can vary due to sending the cards that would let Dealers do the big damage to teammates or choosing to go for a play themselves, so they are the closest thing to a wild card character type.

After Norma buffs, Dealers will receive a +2 hand limit bonus and +1 HP, so is a good role to play for characters that could benefit from an extra point of HP such as Peat or Pilot Marc. At level 10 Summer Games role hyper is unlocked, which provides a stock effect of making the next panel landed on a guaranteed draw 2 cards effect while ignoring any effect of the tile the player lands on. Due to giving up the character hyper, Summer Games might not be picked super frequently depending on the character used. This is one of the most niche role hyper picks since this is best used as a card to pass to a specific teammate for more drawing power for them to get a specific hyper, but each Summer Games drawn will take away from the hyper pool in the deck which is why it is a tricky pick more often than not. At level 5 the Demand role ability is unlocked, which does the same thing as the role hyper except that it is only valid on the turn it is activated in and is not a Stock effect. This is an important tool to open with in games and a form of protection in the later game against bad tiles the player wants to avoid such as damage, drop, or boss tiles so should be used more wisely the longer the game goes on. If you trigger a trap that warps your character or you get KO'd before your turn ends, Demand will not trigger and you won't get 2 cards.

Norma Buffs:
2: +1 Hand Limit
3: +1 HP
4: +1 Hand Limit




Vanguard: Finally a new role in 2025 huh? Crazy stuff. Gonna be a WIP on things Vanguard related for a while until I play more over the following week since it just released on October 21st 2025. Vanguard(VG) is like a passive-aggressive role where you use your teammates as connections to enemies whenever enemies are the ones to challenge to battle. The first ability known as Reinforce(RF) acts like Bourbon's hyper where an enemy challenges an ally and the reinforcer fights ahead of the ally to do a "Reinforced Battle"(RB). If the Vanguard survives this battle, the reinforced ally gets +1 in ATK DEF and EVD for the next battle that would've occurred originally. If the VG dies though, the next ally only gets +1 ATK for the next battle. Also, the Vanguard can use Interrupt at the start of a Reinforced Battle (8 turn cooldown) where if the Vanguard survives, the battle that would've continued on to the next ally is cancelled. It's a strange effect that you don't always want to use, as it can cut off an Attacker that otherwise would've wanted to fight. It is also worth noting since it is easy to miss or glaze over, but reinforcing anyone and keeping the RF up will apply -1 MOV to the Vanguard while it is out, and there is no way to remove an active RF except for the target to be challenged by an enemy.

The characters that benefit most from this role are those not lacking in DEF and have at least neutral stats to get the most out of any stat buffs. Interestingly enough, the VG entering a RB will also retain the traits of character and role passives, for example with Vanguard Castle: RF'ing an Attacker will let VG Castle attack first like the Attacker would have, but any other role the Castle RF's, the Castle will go 2nd and can't counterattack as usual. This role favors pairing with an Attacker to get the most out of it and characters that are willing to fight knowing the stat boosts they are expected to get in a game, as this role is heavily stat driven likely to get into more battles than average with proper planning ahead. -DEF characters so far are the hardest to use under this role as they sometimes can’t tank a single attack I.e. Beach Breaker with +3 ATK.

At level 5, role ability Bolster is unlocked, which removes any effects placed on a chosen player by boss or minions, giving 1 HP plus additional HP for each effect removed. Overhealing over max HP is possible with yellow colored number to signify overheal HP. If target has no effects stocked, then Cleansing Aura is stocked on the target instead which blocks the next effect from being applied to the target ally. 5 chapter cooldown.

The role hyper unlocked at level 10 is Vanguard of the Burning Sands which removes all effects on self and allies placed by bosses or minions, and all allies gain 2 HP as well.

Norma Buffs:
2: +1 DEF
4: +1 EVD, +1 HP

As requested by mariosonicman1, I will begin detailing changes characters and/or cards receive between each update or new release (if any changes) in a new section here.

Tons of characters got adjustments to role ranks, way too many to list here. The most notable change based on all I've seen over time playing casually was Dealer Krila and ALL of Nath's roles having their role ranks raised, many supports got slightly buffed.

Kiriko
Hyper now restores previously burned max HP for Strange Medicine buffs; 1 max HP restored for each unit KO'd

Yuki Dangerous
Too long, co-op rework

Suguri 46B
*Gained +1 to ATK stat, no buff to ATK from hyper anymore.

Shifu Robot
*Changed passives again, too long to summarize here.

Aru Scramble
*Can now choose when to use Santa's Gift to send a random card to a random teammate.

Ceoreparque
*Witch's Hair Lock now costs 0 stars to use, down from 10.

Nico
*Miracle Walker now costs 0 stars to use, down from (cards x 5).

Shifu Robot
*Changed Passives:
*Start and revive with 2 HP after 2 turns (up from 1 turn) + Burn Out stacks
*If active(not KO'd) and below maximum HP for three consecutive turns, heal 1 HP. (Healing buildup turns are not counted while at max HP anymore)

Iru
*DEF increased to 0, up from -1.

Mei
*White Christsmasher range increased from 0 to 1 and also discards your hand on use.
*True White Christsmasher range increased from 1 to 2.

Cuties
*Now gains extra stars from bonus panels instead of extra stars from all sources.

Suguri (46 Billion Years)
*Double Damage cost reduced to +50% (down from +100%).

Mescal
*Added passive: If one of Mescal's Pirate Crew Members are KO'd, they will not spawn to protect Mescal for 3 chapters afterward.

Alicianrone
*Now gets +1 EVD vs +1 ATK and +2 EVD vs +2 or more ATK, up from +1 EVD vs +2 ATK and +2 EVD vs +3 or more ATK. Small buff but not too drastic.

Arthur
*Passive star bonus per start of each turn x number of shops changed to passive bonus only applied on Bonus panels or enemies landing on Toy Shops (enemies landing on shops needs testing in Co-op.)

Halena
*Stars gained from landing on own home changed from (Lvl x 3) to (Lvl x 2). A small nerf in the grand scheme of things but not too bad.

Iru
*0 DEF changed to -1 DEF (undone in April Fools 2022)
*Iru no longer goes 2nd after challenging an enemy to battle, changing her dynamic quite a bit.

Lone Rider
*0 DEF base down from +1 DEF base
*Passive changed from rolling 6 or higher to activate Lonely Road buff to now requiring a total roll higher than 6. Lonely Road now gives +1 DEF in addition to +1 ATK and +2 EVD as originally.
*Upshift cost increase from 5 + (5n active stacks of Upshift) to 10 + (10n active stacks of Upshift). This is still a useful ability but the cost has essentially doubled so requires more consideration to use.

Suguri 46B
*Can now play an extra card on the same turn that her hyper Observer of Eternity is used.

Tomomo (Casual/Sweet Eater)
*No longer loses Ice Cream from battle KO! This is a huge help but Tomomo still needs luck of actually getting her hyper into her hand.

Tsih
*Tsih's Stealth On hyper no longer triggers Encounter or Boss panels when active, giving it an additional defensive use in some situations but losing out on an easy access to attack the boss.

Hyper: Full Speed Alicianrone hyper can be better compared to role hyper with some luck as it helps with rolls and deals damage to any enemies along the way and Rone can also challenge an enemy along the way, but it is prone to RNG bad luck. Hyper choice is up to if you need a chance at big movement + some damage or more consistent support out of your hyper.



Hyper: Self-destruct only works well with some roles. With Guardian and Support the role hypers may work better since she will help the team more directly and may not be able to make use of higher attack the same way in those roles as Attacker or Avenger would.



Hyper: Arnelle's Intelligence Officer hyper is her main draw to picking her and when used in battle will vary based on the top deck card, which is visible if Arnelle has this hyper in her hand. It can be valuable to know for a player to draw the next card or save it for another teammate.





Hyper: Arthur's Toy Shops no longer earn stars passively, but you can still draw cards from them. Arthur won't be pulling big punches outside of Avenger role and wants to focus on getting Toy Shops on home panels and avoiding unnecessary risks due to his bad REC. Note that other players' traps can delete Toy Shops, so be careful pairing Arthur with characters like Krila or Yuki D. Role hyper on Arthur isn't worth.

Hyper: Her character is normally too good to ignore unless facing specific bosses like Hyper Ropochi where you may need the extra revive power with Support or Summer Games protection with Dealer.



Hyper: Aru should stick with Santa's Job character hyper due to its ability to net stars while passing cards to teammates. Aru won't be throwing any big punches without Avenger role, but Santa's Job gives her a special niche gaining some stars in any role. At lower Norma levels or if the team is doing poorly, her hyper might end up a dud if she has cards too high of level in her hand that she can't pass. This also pairs well with a Dealer giving her cards to hand out for free stars and can be surprisingly cheesy to maintain a supply of stars as long as Aru keeps her hyper in hand.



Hyper: Repa's Witch's Hair Lock hyper is decent but not foolproof since it will not stop a boss from playing a card, only from moving with its next movement roll if it is the target of Repa's hyper. Sometimes it is worth considering going with role hyper if you needed something different than just freezing an enemy from moving for one turn.



Hyper: Chicken's Golden Egg hyper is useful to get more stars when placed on a home panel for easy access and grants stars to the team even if an enemy steps on the trap unlike Piggy Bank! (clarified thanks to the Gamepedia Wiki for this game) Whether or not you want Golden Egg or a role hyper would be a tossup between getting stars sooner if Golden Egg is drawn, or using role hyper which can be useful even after Norma 4/5 is reached where Golden Egg no longer remains as useful.

Hyper: Chris' Chef and Manager hypers are decent barriers attacking on behalf of Chris, but getting to Manager hyper could be blocked due to not getting the right cards needed. Due to Chris' inability to challenge enemies without Chef or Manager, it is ill-advised to use role hypers with Chris or you will lock out her main defining trait from play.


Hyper: Despite the text, you can still be attacked by any mobs or bosses that walk into you and always attack as that is not considered a "challenge" in OJ terms. Unfortunately it is expensive and can be very random whether or not stars are stolen successfully depending on the boss played against. You cannot target a user under Special Stage with say, Mimic in the event you wanted to copy their hyper, despite the card text being updated and not seemingly mentioning that allies cannot target each other while this is active. Role hyper is much better against bosses who don’t hold stars like normal such as SB and SC.



Hyper: Stick with Ellie's Miracle hyper most of the time and pack a President's Privilege alongside her character hyper. Role hyper could be considered, but not packing her character hyper dampen's Ellie's potential quite a bit.



Hyper: Now that Air Support has changed to Air Strike, Fernet has clear hypers she should pick depending on the boss. Air Strike is better for Haruo, Summer Beast, and Swimming Coach. For other bosses, she should consider role hyper instead.

Hyper: Castle's Immovable Object hyper only has very specific uses and would typically be better off playing with role hyper. With Avenger it is a legitimate choice between character and role hypers as they are both good.



Hyper: Hime's Binding Chains cuts EVD of all enemies on the field for two turns and leaves them unable to move on their next turn. Being able to cut EVD is a rarity and makes it very good against bosses with mobs such as Haruo or Summer Beast to pin them down and KO them with less chance to evade or escape. Despite the card text, the boss WILL still play its incoming card after Binding Chains is used. Everything else will be skipped including movement and specific things like Summer Beast's revive roll however. Role hyper might be considerable against bosses that lack mobs.



Hyper: Iru's Extended Photon Rifle is useful for melting the shields of Ropochi or M10 when facing off against those bosses. It also has a more notable use to melt Goalposts and maybe other mobs of Swimming Coach and is the crucial pick vs this boss. Against other bosses, it becomes more preference what you think will be better for you.



Hyper: Islay's Rival Hyper expensive but allows the user to attack an enemy and go first with +1 ATK so can be a lifesaver or a way to clutch out a win. Her character hyper is good if Islay goes Attacker or Dealer, but role hypers are considerable in her other roles.

Hyper:: Kae's main hyper is more considerable in most roles due to the potential to stack lots of allied units at once with Blazing should the opportunity present itself, but role hypers are also considerable minus Dealer.



Hyper: Kai's Protagonist Privilege hyper is extremely good, letting any character using the hyper attack first and prevent the enemy from counterattacking once per battle for 3 turns in most situations.



Hyper: Kiriko's Final Surgery hyper can get your team killed if played at the wrong time, but it will net a nice chunk of stars and give -2 REC to teammates KO'd by it using their low HP to get stars. Role hypers are much safer than Final Surgery since FS requires such extreme conditions not favorable to aim for and role hypers can contribute more directly to the team without sacrifices...

EXCEPT with the addition of Swimming Coach, Final Surgery is suddenly EXTREMELY useful to KO all of the goalposts and other weak mobs on the board for big star gains, making it overpowered against Swimming Coach unless going for the Hyper achievement where it cannot be used and role hyper should be used instead.





Hyper: Krila's hyper Plushie Master is very good due to its cheap cost and multiple benefits when an enemy lands on a trap. You will always want to use this hyper and not the role hypers. This lets Krila play her best roles and support her team seamlessly.

Hyper: Crystal Barrier is defensive to a fault where it doesn't help the team win the game sooner so role hyper might be better or more worth the stars depending on the role or the strategy Kyoko and her team are aiming for.



Hyper: Kyousuke does not have the strongest character hyper by a wide margin and drawing multiples can mean dead hypers that potentially see no use so is an awkward pick at times.



Hyper: Kyupita's Angel Eyes hyper is a cheap effective hyper, unusual in that it will provide stacks of stat buffs active only when the user attacks first in a battle. In other roles not focused on attacking, role hyper might be more useful for the rest of the team.



Hyper: Lulu's Lucky Egg hyper is expensive, has a small risk of being a dud, and also restrictive as it is only usable when the user has 2 HP or less remaining. Her hyper can be strong but less expensive role hypers exist as an alternative for those scared of bad RNG. President's Privilege is highly recommended to pack alongside her Lucky Egg hyper.

Hyper: Marc's 16x Big Rocket hyper is expensive late game, but damage from anywhere on the board equal to current Norma level with any role she plays is not a bad thing to have. Packing a President's Privilege when selecting 16x Big Rocket is definitely not a bad idea for a chance to save stars later in a game if you can get both cards in hand.





Hyper: Pilot Marc's hyper has a smaller damage cap compared to regular Marc, but is more cost friendly with minor drawbacks that the player can work around. Character hyper is the good pick for Pilot Marc, also notably better against Swimming Coach compared to regular Marc due to her hyper's flexibility.



Hyper: Poppo's Ubiquitous hyper is the pick of choice to gain stars with and get to Normas faster, but it is almost pointless versus Swimming Coach and Summer Beast since they don't ever hold a surplus of stars as other bosses do. Against these two bosses role hypers would be better to use instead, but if you want to use role hypers Mixed Poppo is better to use if you own her as explained in her section.



Hyper: Mixed Poppo's Subspace Tunnel hyper is a double edged sword since she can generate stars and draw cards when warping, but it can be a MIXED bag due to random warps for all units leading to unexpected situations. It is worth noting Mixed Poppo is better than Poppo if you wanted to use a role hyper since they have identical stats except Mixed Poppo has a free passive she can benefit from unlike regular Poppo.

Hyper: In Co-op mode Maynie's Raging Madness hyper requires much more time to setup Rage Counters to reach higher stats, leaving Maynie to be a late game trump card once she is ready to go. If she uses a role hyper she can't make use of her Rage Counters so her character hyper should ALWAYS be picked.





Hyper: Mei is one of the strangest characters in Co-op as she is only useful for Red and Blue. Her True Christsmasher hyper complements characters holding Red and Blue, but also got hugely buffed in April Fools 2022. Stick to her character hyper since Mei is better able to get R&B copies faster now.



Hyper: Mio's Magical Inferno is brutally expensive in Co-op even if it can be a nice play to deal 5 damage to a boss and all mobs in the line of fire. Role hypers are more practical and help save stars in case other characters with expensive hypers are also played. Mio should consider packing 1-2 president's privileges if she intends on using her character hyper.





Hyper: Mira's Leap Through Space hyper typically does not have a major impact except on split boards or to set up pinning down important mobs of Haruo, Ropochi, or Star Devourer. Role hyper is often a better choice outside of those specific moments. Mira has equal role grades as Hime and Sumika while having a passive unlike those two, so Mira is noteworthy for being the most packed among the three (albeit very minorly) if wanting to use a role hyper.

Hyper: Miusaki's Solid Witch hyper is better than most role hypers Miusaki could pick, stick with Solid Witch in all roles except Avenger where role hyper is worth considering as well especially after her passive nerf.



Hyper: The main drawback of Nanako's Deploy Bits hyper is that it is wildly volatile and inconsistent, so role hypers are an option if you don't feel like gambling.



Hyper: Nath's Another Ultimate Weapon is so potent that it is the main hyper that should be considered. Against Summer Beast or Swimming Coach she might want to using it without too many stars in stock or using role hyper instead since their full HP is separated by lives or impossible to cheese.



Hyper: Natsumi's Cooking Time hyper is a solid hyper that can heal your team a ton of HP in a flash. Natsumi never uses role hyper because this hyper is too good to ignore since drawing it will provide more opportunities to heal the whole team at once.

Hyper: Unfortunately Nico's Miracle Walker is a giant RNG fiesta with wildly varying results which will only get more random as more characters release, so is considered a chaos card instead of something that works with reliability. Role hypers are never considered for Nico since Miracle Walker is the one thing she has that makes her stand out and can change the entire game randomly.



Hyper: NoName's Overseer hyper is expensive but acts as a pass to get out of a boss fight and let Shifu Robot take the place of the user for one battle. Hyper choice is a toss up since Overseer can drain stars quickly if other players also have expensive cards to use.



Hyper: Peat's stats unfortunately leaves more to be desired for how high his REC is and he needs to rely on his character hyper to throw heavy attacks at enemies and survive an attack afterward. Peat should never use role hyper since he NEEDS Blue Crow to function.



Hyper: QP's Hyper Mode hyper is generally the hyper of choice you would want to pick with QP, but there are merits to role hyper for Avenger as well.

Hyper: It may be easy to misread, but in Co-op QP's Sweet Guardian hyper ONLY provides two copies of the card “Pudding”. Devoting your hyper to these might not be helpful to the team killing the boss faster or surviving a big boss attack/card so role hypers may be a better fit for her more often.



Hyper: Roboball's Reflective Shell hyper effectiveness is usually limited to non-Attacker users or Sherry since it requires going 2nd in a battle.



Hyper: Saki's Big Bang Bell can be a beast if given time to grow, but needs Path Blockers to make an enemy land on the trap reliably. Saki could try using role hypers, but at that point there would be other characters with better stats that could be used instead. Her lower role ranks help to better fit at least one Path Blockers into the deck, but it is still expensive. Saki's main issue is that she's exceedingly card point hungry for Big Bang Bells that may never see the light of day or be triggered at all in a game.



Hyper: Seagull's Jonathan Rush is ok in Co-op, but this hyper is a toned down version of Islay's hyper. Seagull's hyper costs 20 stars and gives -1 DEF to the enemy while Islay's costs 30 stars and gives +1 ATK to the user. Note that anyone using this hyper isn't considered a challenge, so it will not activate Iru's 1 damage passive for example.

Hyper: Sham's Delta Field is changed in Co-op to a battle card that makes the enemy roll 1 on dice(s). This is a pretty decent hyper to lower damage in battle or get an easy evade and then more easily damage afflicted enemies.



Hyper: Sherry's Whimsical Windmill hyper is risky to use due to the 30 star cost and how the user has to attack 2nd when used unless used by a non-Sherry Attacker. Its use is limited as the user will only fight the boss with this hyper and no mobs, so role hypers are often the more reasonable picks unless Sherry is playing Dealer where the hyper has some gimmicks.



Hyper: Shifu Robot's Turbo Charged hyper has the potential to do tons of damage but is incredibly risky because it brings the user down to 1 HP and all stacks are removed immediately if KO'd. Portable Puddings and Puddings need to be packed and Guardians and Supports should be ready to keep the user alive if this hyper is to be used. The role hypers are much safer and usable more often across all roles.



Hyper: Sora's Extraordinary Specs hyper is so strong that she should always use her character hyper over any choice of a role hyper. It gives users an opportunity to become a relevant threat at key moments under any role.

Hyper: Similarly to normal Sora, Military Sora's Awakening of Talent hyper is so strong that it should always be picked over any role hyper. Military Sora's hyper is a bit more flexible and a little cheaper than Extraordinary Specs but rolls a guaranteed 5 and can be used in battle as a battle card and not just as a boost card on the field.





Hyper: Star Breaker's Star Blasting Fuse hyper brings so much potential DPS to the table that she should avoid role hyper except with Support or Avenger depending on the boss.



Hyper: Store Manager's Banned for Life hyper is noteworthy in that it is the only hyper that has the effect of negating the boss' next action/card, and only costs 10% of your current stars. This is the only hyper that should be picked as role hypers cannot be played anyways. Swimming Coach mob spawns cannot be interrupted, but Haruo is susceptible to having one of it's chicken spawns blocked through Store Manager's hyper played right before.



Hyper: Suguri's Acceleration hyper carries some risk to it but has a chance of being a huge game changer so should be the main hyper Suguri uses except in some extreme cases with Hyper difficulty bosses.

Hyper: While 46B's Observer of Eternity hyper can be extremely powerful, it is wildly random and can be expensive to play out due to stars needed to abuse double damage effects. On another note, If 46B uses President's Privilege followed by a double damage activation effect, the player still pays the entire 150% cost of the played card and President's Privilege is also wasted. 46B is a wildly busted pick on days that the Joker mixer appears since her double damage abilities are free when Joker is active.



Hyper: Suguri Ver 2's Revival of Stars hyper is very weak in Co-op mode as the hyper has no effect on existing Boss panels or Boss Home panels despite the card description. Role hypers will have more long term impact on the game so you will want to opt for a role hyper more often than not unless you value a hyper that is more useful earlier in a game.



Hyper: Sumika's Reproduction of Records hyper is one of the most advanced cards which normally requires paying attention to the deck and cards drawn constantly to get the most out of it. Getting familiar with the specifics on how cards affect or don't affect the discard pile is key to getting the most out of her hyper. It is highly considerable but role hypers for consistency are an alternative if you don't like the nature of her character hyper.




Hyper: Sweet Breaker's Melting Memories hyper was changed in Co-op to allow her to be more engaging while differentiating her from Store Manager. Now she shuffles the boss card order and gets +1 stat buffs against existing enemies for 3 turns with the same cost of (X Stars/10) as her old hyper. It isn't a super powerful effect and the shuffle could make things worse for the team, but the X/10 star cost means it's usable almost anytime which still makes it valuable.

Hyper: Syura's Beyond Hell hyper is completely free to use and can be played any time, so is useful even as a form of defense if the user has only lost 1 or 2 HP. Beyond Hell should be the main thing Syura picks due to it's flexibility.



Hyper: Teotoratta's Beast Witch hyper may not be a very powerful hyper, but at least it works now after the Pool Party update. Before it only worked on Encounter panels and not Bosses or their mob monsters. That is switched around now so Beast Witch works against Bosses and mobs + boss cards that would drain stars, but not Encounter panels. Role hyper is still typically the way to go, but at least now Beast Witch isn't useless as it is can be a safeguard to prevent losing early stars.



Hyper: Tequila's Do Pirates Fly in the Sky hyper is changed to be more direct and consistent instead of spreading traps across the board, it makes 2 pirate crew members challenge a random enemy. Its a surprising hyper which allows nearly risk-free attack attempts on enemies but a little pricy.






Hyper: This duo's hyper should always be picked over role hypers or there's little point in bothering with them. Mimyuu will plant Execution cards which heal 2HP for whoever draws them, while those same cards will convert into Waruda Machines if drawn by Tomato which can be a very strong battle card.

Hyper: Not using character hyper for Tomomo Casual would be terrible as role hypers would lock out access to Miracle Red Bean Ice Creams aka the big reason to play this character. NEVER ever use role hyper. In Sweet Eater form, her hyper turns into Magical Revenge which can be decent if an opportunity presents itself.



Hyper: Tomomo's Magical Massacre costs 40 stars instead of 20 in Co-op, but is a good hyper to use when a teammate is KO'd, which will deal 3 x (number of KO'd teammates) worth of damage to ALL enemies. This means most mobs can be wiped entirely if 1 teammate is KO'd(not Goalposts unfortunately). This is a really handy utility for the team which Tomomo should use.



Hyper: Tsih's Stealth On hyper is changed in Co-op so that the user cannot be targeted by Boss Cards/Abilities which choose random targets for 3 turns but the user will still be able to be challenged to battle by an enemy. Examples of cards that can be avoided include Haruo's Final Warning, M10's Engage, Jonathan's Rush and Double Rush, and Ropochi's Big Po Special. Against Star Devourer, this hyper would only avoid Snatcher. As of Poppo Event 2021, Tsih no longer triggers encounter or Boss panels while her hyper is active which is a mixed bag.



Hyper: Yuki's Gamble hyper is risky and leaves her down for a long time due to high REC if she is the one targeted by the hyper. A character at full HP/1 less than max can survive if they are hit while a Guardian shield is protecting them. Role hyper can be used for a safer hyper or use Mimic to get a hyper from another teammate if you don't like RNG.

Hyper and Miscellaneous Extra Notes: Evil Mastermind runs off of trap cards and you can't see what cards it places, which sucks because there's too much randomness as a result. Role hyper is more immediately reliable across all roles for Yuki D since her hyper isn't going to be consistent and can even backfire at times with enemies landing on traps such as Piggy Bank or 2nd Poppo Bank. Arthur shops given to Yuki D used to be a strat to build up wins, but this was changed so that only enemies stepping on a trap Yuki D laid provide the win bonus now.





Hyper: Yuuki's Angel and Devil Hand hypers may be a bit pricey, but being able to swivel between two hypers passively depending on the turn number and them both being very strong effects where it is easy to net more stars after use regardless of role makes these hypers that should be picked 100% of the time. For example, Devil Hand costs 30 stars to use, but hitting a boss with enough HP such as Jonathan will deal 5 damage and return 50 stars, so you NET EARN 20 stars if 5 HP of damage is done to an enemy. Devil Hand deals damage calculated normally which is important to know as the shields of M10 or Ropochi will reduce incoming damage of this hyper (this means 2 damage only and -1 shield if used on a shielded boss). Devil Hand is also prone to RNG target selection when multiple enemy units are on the field, but overall it's still a pretty good hyper, it just can't cheese shielded bosses into oblivion anymore.

Since reorganizing all of the guide to account for future DLC releases is a nightmare, starting with Halena and Cook release the following releases will be organized by the order which the following DLC characters are released.



Hyper: Halena's Safe Journey is noteworthy as it will negate (damage + linked effects) from various boss cards (credits to SomeGuy712x for this clarification). For example, M10's EMP will do 0 damage and the debuff will not apply. Safe Journey will protect from Jonathan's Dive around the marked red Dive panel, however if the user is on the red panel Jonathan lands on, the KO status is not prevented by Safe Journey as it isn't calculated damage. This hyper must be used wisely and could be troublesome if playing with other characters with expensive hypers or against bosses that can take stars away easily such as Star Devourer or Ropochi.



Hyper: Now that Cook's hyper ends on KO, how useful it is for the cost is questionable without lucky rolls landing perfectly on bonus tiles. At the very least users can now visit their own home without losing Guidance in Co-op mode.



Hyper: Upshift is overall an affordable hyper which increases in cost depending on the number of stacks of Upshift currently on the user. It's a hyper with a simple effect that would be hard to turn down for a role hyper.




Hyper: Merchant's Zealous Salesman has two purposes as a small star gain tool or to unleash a high Attack after stockpiling Freights. The former is easier, while the latter is harder so the player will need to use their best judgment to determine which is a higher priority depending on the flow of the game.

Hyper: New Nobility is weak overall but it has no cost to use. This plus Affluence would be the main hyper to use since her statline isn't really noteworthy to run alongside role hypers. It is also worth noting that if regular Fernet gets this hyper into her hand, that version can also use both hypers as well.



Hyper: Dance in the Moonlit Night is a big risk hyper capable of potentially big damage if the user can evade a big roll. Role hypers could be more consistently useful, but switching to a character that isn't such a glass cannon might be easier if wanting to use role hypers.



Hyper: Little Magnum gives Tequila's/Avenger's revenge damage buff for the battle it is used in, meaning the user needs to attack 2nd to make the best use of this card. It works well enough as long as the user can survive a fight since this card doesn't increase survivability.



Hyper: Twilight-Colored Dream is changed in Co-op so that all allies gain +1 ATK during its duration when fighting on boss tiles. It's small but can help speed up closing out the game. For support type roles, Malt may also want to consider role hyper depending on the boss.

Hyper: Ideal World is a really solid hyper to protect teammates or the user from battles for a couple turns, role hyper is worth considering as well if you needed more powerful effects tied to the role being played.



Hyper: Star Collector is not really powerful but affects the entire team for 3 turns so can randomly net a bunch of extra stars for free, and the main reason you would bother picking Reika. Reika currently has no good use in Co-op due to the absurdly terrible combination of 7 REC base and 3HP. It is too bad for any role to overcome and Star Breaker is better in all roles with the same ATK and REC but 2 more HP.



Hyper: Torrent of Magic could be useful for anyone using it, and is the main chance Watty has to try and abuse Hardened Scales since the passive is more limited without Watty having extra DEF. Role hypers might be considerable for a different effect over playing Watty's stat buffing mini game.



Hyper: Comically enough, anyone using this hyper can be pet. It's main use is defensively so is better used for characters that need it like Supports or Guardians instead of Attackers and Avengers who are the bulk of the potential damage on a team in normal situations. The main weakness it is is that if Pomy/ally is on a bad tile, someone has to interact with that first before reaping the benefits of petting their ally. Could also lowkey be a new useful addition for Hyper Jonathan Chapter 50 challenges.

Hyper:
Via the OJ wiki: Non-hyper Sweets type cards include Saki's Cookie, Pudding, Dangerous Pudding, Mio's Christmas Cake, Red Bean Ice Cream, and Portable Pudding. The usefulness of Creator's hyper will be somewhat dependent on your team, but her character hyper is a good bet if you aren't sure which to stick with especially if she is Dealer.



Hyper:
There is some RNG to her hyper, but it can be really strong with luck so she should stick with it instead of role hypers.



Hyper:
Her character hyper can be strong but can be difficult to setup for only one battle’s worth of payoff. Role hypers would be easier to use, but doing so nearly kills the point of picking this character without taking risks triggering her passive.





Hyper:
Christmas Inferno is a wildly volatile card that can wreak direct havoc on the boss + all minions at the cost of bringing the user down to 1 HP. Mio herself doesn't have the widest HP pool or a good REC stat so typically others with better of either stat will squeeze a bit more damage out of this hyper.

As a bonus more KO'd members on use means more Mio Cakes afterward as well. They unfortunately cannot revive a teammate, but the 2nd part where healing an active ally for 2 HP also healing Mio has no major downside, so picking Mio solely to heal would only be for specific situations like an Avenger trying to time their Beyond to go off and they are at low HP already.

Hyper:
Make-Believe Prison Break is typically the hyper of choice due to it's uniqueness and multiple effects that can come in clutch in a way no other card in the game can.





Hyper:
PJ Krila's hyper is an oddball going from Threats to Slumber (Gift) to Breaking of Slumber (Event), but the payoff in the long run is worth for dealing damage from anywhere on the screen so would be the hyper of choice generally.



Hyper:
A bit of an odd hyper in that Mother Power is very cheap to use starting at Norma 1 but takes longer to proc at higher norma meaning it is harder to get the full HP heal especially at norma 4 and 5 where you have to plan several turns ahead without dying to get it to work. The tossup between hyper choice basically comes down to whether or not you want something that works better at earlier norma or more consistency later in a game with a role hyper.



Hyper:
Dark Lulu's hyper has two good effects and one meh effect, but the two good effects are worth trying to gamble for as they can completely turn a losing game around or save with an epic clutch with rare effects most cards and hypers can't do in the blink of an eye: 3 HP damage to all enemies or next boss card skipped.

Hyper:
Quite a bit different but more rigid than regular Ellie's hyper, only giving ATK buff when attacking 1st and DEF + EVD buffs only when defending. Most roles she will probably want this hyper packed with President's Privilege, but role hyper for Avenger isn't a bad consideration either.



Hyper:
This hyper is a bit odd in that it becomes more expensive per norma without becoming better. Deciding when to use it is key and you have to watch for anything that could kill you such as a field effect after it brings you to 1 HP. It is extremely strong though, so it should always be packed except with Avenger where you may favor role hyper.



Hyper:
Heart of Resistance is pretty much the stand out gimmick for Bourbon and the main reason to pick him IMO, so this should be packed in favor of role hypers for this character.



Hyper:
All Guns at the Ready has disgusting potential if you can manage to play a lot of cards before using it. It is tricky to setup because of the requirements but will contribute a ton to dealing damage to enemies on the field. There is an RNG factor that can make it not do exactly what you want to do however.

Hyper:
Super Youth Time is a little expensive, but has potential to clutch out random wins in ways that hardly anyone in the game can match unless the player gets horrible luck. IMO should be the usual pick for hyper selection but the role hypers are an option for those concerned about consistency.



Hyper:
Chuu's hyper is relatively cheap and gives a flat ATK buff based on current level, while the hyper becomes more expensive to use the higher level you are. All in all not bad at all but role hypers may be good to consider if not using Attacker or Avenger Chuu. Extra diligence is required to ensure someone does not forget that stars are not earned when KO'ing enemies with this hyper which is mostly noteworthy against Big Poppos.



Hyper:
Hype Bringer is a pretty good card even if it is expensive later in a game. REC is the biggest enemy to the team as it is the thing that can actually make you lose, so this hyper basically ensuring that as long as you have stars to pay that it is impossible to lose, is a very powerful safety net.



Hyper:
Intellectual-Sounding Bluff is an incredibly unique card in it's flexibility of allowing the team to draw more cards after use, regardless of board position of each unit. It is hard to say no to this in favor of a role hyper on Kanata, so ISB is normally better to use given it's potential.

Card Points at Level 10: A: 15, B: 18, C: 22, D: 26, E: 30

(Assuming Level 10 in a role, optimal number of 5 point cards that can be brought: A: 1 or 3, B: 2, C: 2 or 4, D: 4, E: 4 or 6)

100% Staples: Dinner, Accel Hyper, Pudding
Cards that A rank characters should typically plan to pack one of more often than not. Dinner is a big deal because it will heal everyone 3HP for a cheap cost, so it is common for everyone that is not an A or possibly B rank Attacker to pack one. Accel Hyper is a potentially powerful attack buff so would be good for Attacker to pack, but anyone who gets it and attacks first can use it to try to make a clutch play. Pudding is free once Norma 4 is reached and always a good card to consider bringing especially for an Avenger.

Secondary: Passionate Research, Serene Hush, Shield Counter
These are easier to pack for those that are C rank or lower, but are worth considering if you are B rank and need something specific important with these cards as well. Passionate Research is a cheap way to try and get hypers faster where it will be a big help to do so. Serene Hush can be a lifesaver to block battles for one turn against bosses with strong fighting cards such as Jonathan or M10. Shield Counter is a good late game defensive card that can deal several HP damage to Jonathan and Summer Beast with high attack buff stacks and also very helpful against Swimming Coach's Balloon Bullies trying to use Encourage.

D or E Role Extras: Lucky Charm, Holy Night, Portable Pudding
These may not be terrible cards, but they are a bit more situational or more like icing on the cake and good cards to throw in for characters playing lower rank roles. Lucky Charm used to be a terrible card because if the boss had a bad card that needed to be dealt with, Lucky Charm would block you from playing something more helpful to counter the incoming card that turn. Now with boss card history visible starting with the Pool Party update, Lucky Charm is much better to pack for extra star gains with more foresight on potentially dangerous cards incoming from the boss and time to discard it if needed. Holy Night is free and will give extra stars over the course of a game sooner and Portable Pudding can be good for Avengers or emergencies, or as of the Sweet Gods update can act as a consideration for QP Dangerous to hold it unused and heal for 1HP when achieving a battle KO.

Situational: Metallic Monocoque, Super All-Out Mode, Path Blockers, Mimic
These have situational uses that would be dead weight against some bosses and should be changed out according to who is fought. Metallic Monocoque is a huge staple against Jonathan and would be good to pack against this boss even at the cost of another 5 point card on higher difficulties. It is also helpful against M10 Robot but may end up draining tons of stars when the Robo Beam card takes off late game. Super All-Out Mode can be extremely risky since it also gives a buff to the boss and mobs, against Summer Beast or Swimming Coach this could kill your team so must be used carefully. Path Blockers is too expensive for something that invests into the Trap archtype of cards which are the weakest types of cards in Co-op and only situationally worth picking.

Mimic is expensive and usually hard to consider when everyone can pick between two different hypers they want as it is so typically people already will have good hypers they want most of the time. If a Dealer keeps drawing the hypers people want and deals them out then Mimic almost has no point. Mimic's main notable point is lucky Arthur/Nico shenanigans where they can potentially get multiple copies of another player's hyper if they can draw Mimic after setting off their own hypers. Despite all of this, it might still be a decent consideration with coordination to potentially have a teammate mooch off of one character's good hyper like Suguri's or Sora's to help kill the boss faster.

Bad: Mix Phenomenon, Price of Power
Mix Phenomenon is too random and doesn't work very well when Terror boss tiles override any changed tiles every 2 turns anyways. It is also potentially dangerous on boards with dead ends if say a warp panel was changed to something else and the team was trapped for a few turns.

Price of Power is too expensive and pointless when there's often no need to pay more stars to play higher than current Norma level cards in a mode where Norma isn't a serious problem to achieve. Even if it was hard to Norma, Price of Power would simply delay being able to Norma due to increased card costs for all cards.

(Assuming Level 10 in a role, optimal number of 2 point cards that can be brought: A = 5 with one 5-point card, B = 4, C = 1 with four 5-point cards or 6 with two 5-point cards, D = 3 with four 5-point cards or 8 with two 5-point cards, E = 0 or 5 depending on number of 5-point cards)

100% Staples: Extend, I'm on Fire!, Quick Restoration, Rbits, Reverse Attribute Field, Home Improvement, Saki's Cookie
ExtendREC is brutal in Co-op and Extend helps everyone stay up more frequently. It should ideally be packed when not speedrun farming. I'm on Fire! is a cheap +1 ATK and a Kae staple. Quick Restoration is good to take a hit and heal afterward, Rbits is a cost effective defense boost.

Home Improvement is cheap to play and provides a draw effect on all homes after a roulette. The Home Roulette and bonus draw have no drawbacks to consider unless Halena, Cook, Store Manager, Merchant or Jailbird are used, but is still a very small potential drawback in those instances. Reverse Attribute Field may let someone nullify stat gains the boss has for a battle. Saki's Cookie is a 2 point filler playable anytime for 1 HP heal.

Secondary: Forced Revival, Gentleman's Battle, Deceptive Disarming, Long-Distance Shot, President's Priviledge, Princess's Privilege, Big Magnum, Shield, Tactical Retreat, Serious Battle, Piggy Bank, Windy Enchantment, Encore, Unpaid Work
These are cards that are useful but tend to be more exact in their effects.

Gentleman's Battle is the newest addition to co-op and lets you challenge any full HP target. Good for Haruo Chickens, Summer Beast Seagulls, and to a smaller extent Swimming Coach mobs. Deceptive Disarming in Co-op provides a way for a user to negate the boss' next card ability from being activated if the user can survive a fight against the boss. This is a very good effect but fails if the user does not survive the encounter and is not usable unless the card holder happens to be able to attack the boss the same turn they are trying to deactivate an incoming card. Guardians will have increased value giving shields to teammates with this card existing now, and Avengers can guarantee the effect to go off if they can activate Beyond before going into battle.

Long-Distance Shot is good at finishing Summer Beast lives and pecking away at shielded bosses or a weakened mob. It is also a vital staple for dealing with Swimming Coach Goalposts where 2-3 should be packed against it by everyone. President's Privilege is a good card to pack with characters that have expensive hypers such as Mio and Lulu. Princess's Privilege can now also be played if it is the only card in your hand starting with the 3.5 update, so there is some serious potential to be had especially if a Dealer is in the game since they can deal it to someone who has no cards and net more cards in 1 play, or use it to draw 4 cards themselves.

Big Magnum is strong at the cost of 1HP and stacks with Avenger revenge passive. Shield is ok but prevents counterattack and only usable when defending(Attackers cannot use it most of the time), Tactical Retreat may save your life or is good for Nath to get an easy stack safely. Piggy Bank may help give extra stars with some luck but an enemy can trigger it and benefit from it. Serious Battle is a different functioning Reverse Attribute Field with less purpose.

Windy Enchantment gives +1 move while held but unable to Norma while holding. Encore is filler that is nice to put on a good panel and isn't triggered by enemy units. Dealer’s Demand ability can actually be triggered twice if landing on an Encore card and probably Encore’s biggest reason to be packed and paired with Path Blockers.

Situational: Lonely Chariot, Pet Snacks, Ambush, Dark Side of Business, Play of the Gods, Forced Revival
Lonely Chariot is very hit or miss unless in late game or with Halena + hyper in play or pairing with Metallic Monocoque. Pet Snacks lowers ATK of all enemy units on the field by 1 in their next battle. It is a fairly weak effect for a 2 point card against most bosses, but is considerable vs Summer Beast and Swimming Coach. Ambush is too specific and expensive but has an alternate use of also not moving for the turn. Dark Side of Business is only useful against Star Devourer and even then still part of a risky strategy. Play of the Gods is good to pack alongside Super All-Out Mode, Forced Revival, or Star-Blasting Light to try and cheat them out at a discount. Forced Revival can revive anyone KO'd in a pinch but is also expensive. It's primary usage involves cheesing Star Devourer's Big Poppo with 1/2 HP revival or Summer Beast to make her a little easier to KO again.

Hard to Use Effectively: Lucky Sevens, Little War, Poppo the Snatcher, Accelerating Sky, Lost Child, Bloodlust, Indiscriminate Fire Support
Lucky Sevens is RNG hell as your rolls for any action range from 0-7 while held, leading to odd results not normally possible. It only costs 2 deck points and can still be beneficial if you are feeling lucky or need more Gifts, a considerable choice for +ATK characters. Little War is useful paired with hypers from those like Kai, Suguri, Sora to maximize their effects. Poppo the Snatcher and Accelerating Sky are two cards mainly for Kae buff gimmicks, Lost Child may be ok filler or something that can be passed between multiple dealers in one game, Bloodlust is best for Avenger then Attacker. The wrong character could draw Bloodlust and it see no play meaning a dead draw.

Bad: Star-Blasting Light, Stiff Crystal, We Are Waruda, Poppoformation, Desperate Modification, Backdoor Trade
Star-Blasting Light is too expensive and only does minor damage for Traps not commonly used by bosses. Its most notable use is against Hyper RoPochi since it will destroy invisible bombs laid by the boss, but it could be very difficult to afford playing SBL or pairing it with President's Privilege in time. Another negative aspect is that this will also backfire against trap cards placed by teammates as well, so can be very harmful with characters like Krila or Star Breaker who lay traps for their hypers. Outside of a minor possible use against RoPochi, it is generally bad and can be completely useless depending on the boss.

Stiff Crystal is too expensive at a 20 star cost and unrewarding overall. We Are Waruda is nearly pointless when it focuses only on uncommon traps and better for nothing more than getting a trap off of a home panel or filler to contribute to Cuties' Crashed Events passive. Poppoformation is a Trap that can cripple a teammate very badly and would be very difficult to plan for effectively without Path Blockers. Desperate Modification is investing in a coin flip instead of something with a more consistent effect. Backdoor Trade wastes stars to Norma in a mode where getting Norma isn't a major problem.

Actually Removed from Co-op LOL RIP
Sweet Destroyer got a rework in the normal mode in the Sweet Gods update, but it was also removed from Co-op. It was almost useless before and probably would've made QP Dangerous completely insane after the rework so I can only imagine that is why it got removed.

0 Point Cards

(Filler cards with no remaining points left)
100% Staples: Nice Jingle, Dash, Overtime, Nice Present
Nice Jingle is free to play at any level and simply doubles your next bonus panel roll. Good and best played starting at Norma 2 unless things go horribly wrong in the first 2 or 3 chapters.

Dash is cheap and helps people escape bad situations or get somewhere faster. Overtime is only usable Norma 3 onwards, but can be very useful later in a game when lots of boss panels have spawned, the skipped turn effect can be timed to kick in when Terror/boss panel spam occurs to try avoiding the boss the skipped turn entirely. This is insane to pair with Mixed Poppo on Norma 3 on the Treasure Island boards and get tons of stars to hopefully get the team to Norma 4. Nice Present draws 2 cards at the cost of 10 stars, worth doing as long as you wouldn't have to discard a card after unless you have something that is already dead weight that wouldn't be played.

Secondary: Rainbow-Colored Circle, Here and There, Cloud of Seagulls, Party Time, Unpaid Work
Rainbow-Colored Circle is cheap filler that might be good to give Support characters a ridiculous Evade roll or a hail mary for whoever else uses it, Here and There is a board shuffle that could save the team from a bad situation or maybe not, only way to find out is to try. Cloud of Seagulls is a free coin flip as to whether or not the user or an enemy takes 2HP damage, Party Time is a pricey warp everyone to same panel card that could help setup some serious damage. Unpaid Work is a slightly underrated card that is filler best used against Star Devourer and Ropochi who often take stars from the team. This is especially handy as a filler when trying to go for the cheese speedkill strats against Star Devourer so that it may help you not lose out on norma opportunities.

Situational: Treasure Thief, Heat 300%, BanaNana, Tragedy in the Dead of Night, Exchange, Dangerous Pudding, Indiscriminate Fire Support
Treasure Thief lets you take a card out of other players' hands, which is situationally helpful to pass an important card to someone else that otherwise couldn't get it, but this only picks 1 card in the hand at random and could be a tool to troll with since the other person can't decline giving a card away. Heat 300% is only useful to give Kae a +2 ATK boost thanks to her passive but could be helpful if an enemy lands on it somehow. Unfortunately it got changed from 3 turns duration to stock effect (1) for the next battle only. This damages Kae's max potential a bit but still a considerable card for Kae. Indiscriminate Fire Support is extremely random and inconsistent, but is a whatever pick if you need a 0 point card that can give more opportunities for damage.

BanaNana isn't super good or super bad and might not be able to be used in a good way for some time after it is drawn. It is mainly useful for placing it on a drop panel for protection later or to put it on a Home to let a teammate behind the user stop at Home and go for another roll for whatever reason they might need it (i.e. running from enemies behind, catching enemies ahead). BanaNana works much better with good communication. Tragedy in the Dead of the Night is another way to setup passing a random card out of someones hand which could also be used for trolling. Exchange can come in clutch rarely, but is so awkward to setup in a way that would make it worth it, but it is something for Store Manager to consider packing to try and get cards out of his hand if someone else can draw it and set it up through a miracle.

Dangerous Pudding normally isn't that good since it can affect players as well and weak overall when landed on, but has a niche and occasionally used because of QP Dangerous and some strategies around her. Having a team of multiple QP Dangerous players with Dealer and Attacker followed with other roles and they all cram their decks with multiple copies of Dangerous Puddings means easy ATK gains for each one of these cards drawn.

Bad: I Wanna See You, Mimyuu's Hammer, Sink or Swim, Gift Exchange
I Wanna See You is a Trap that can disrupt the flow of your team and isn't worth using when you can use better more consistently helpful cards instead. The only real use it has is for Halena or Cook to place one shortly before their Home so that someone can land on it later and the user can go Home again quickly to gain additional stars or remove Hunger through their passives.

Mimyuu's Hammer is really weak for 1HP damage for whoever lands on it and only reliable to setup when a teammate has already moved to the tile you're about to move from and the boss is likely to move onto the teammate's panel on the boss' next move as well. When the boss attacks your teammate Mimyuu's Hammer will activate. A weak card to pack and mainly would be done because of someone who hasn't bought many cards yet. The stat drops for the minor payoff with Sink or Swim is underwhelming and honestly not worth over other filler cards. Gift Exchange is completely random how it distributes cards across the team with no control, not a good card to pack and is capable of trolling.

Warp Control is a SHOCKING addition to this game, and a MUST pack for any split boards. Being able to choose your next warp panel is completely insane and is even free to pack so there's no reason not to pack it unless you know you are going to a board that only has two warp panels normally I.e. Tomomo’s Abyss.

Bank of Poppo Generally useful as a source to mill stars later in a game. Placing these on a home lets players more easily land on it while enemies and bosses can't always stop at a home forcefully. Bosses and mobs can reap the awards if they land on it the 2nd time, and it won’t take stars the boss doesn’t hold such as Summer Beast and Swim Coach, so some discretion is needed to get the most out of this and whether it should be packed or not. It is NOT a 100% staple always.

My Wild Friends is an interesting addition to Co-op which will spawn an NPC buddy which is good for general utility especially against bosses heavy with mobs. The buddy you get appears to be based on the pool of NPCs you can run into on encounter panels in the current match. It's other use involves (rudely) spawning a buddy on your tile as a means to block an attack from an enemy behind you after moving for the turn. You can only have one buddy at a time, and activating it will roll a random buddy again with 5 HP as opposed to 4 HP like in Normal mode. Oddly enough these can also act as possible decoys for cards bosses use such as Ubiquitous which would take stars, if the buddy is targeted no stars are taken from the team total.

Contest of Cuteness is a rather strange co-op card, turning an engagement into a safe/tame battle if the user attacked first. This could be useful as a cost to stop on a challenged enemy safely without risking dying to the enemy and when you really need to land on the same tile it is on. This is useless when defending, but Attackers may be able to use this to strange benefit due to their passive making them attack first against bosses.

Nanako's Bit is a bit of a steep card to use in early game, but will prove to maybe come in clutch way later in a game when the chapter bonus makes up for the bit costs.

Rebelllion is an interesting choice as it will require you to use it against any boss besides Summer Beast, but it costs 5 deck points to use meaning it is harder to pack compared to other consistently better cards. Outside of Swimming Coach, it’s just too inconsistent and expensive both in card points and Star cost to really consider normally in my honest opinion.

On July 7th 2025, the Extracurricular Pack was dropped, delivering 12 more cards to 100% Orange Juice while introducing a new card type known as Banner. Banner cards have effects when placed down that affect the game on a wider scale but will be destroyed when stepped on again after being placed down. I won't describe the full effects for each card, so refer to the wiki or in-game if you don't know it off the top of your head. Taking a precursory look and brainstorming with first impressions on the cards so far:

Full Burst seems like a promising card for specific characters like Saki who want to play their norma 3 or 4 cards a bit more quickly or as a possible way to cheat out cards like Super All Out Mode or Forced Revival depending on bosses being fought.

Go with the Flow seems like an alternative choice to Here and There after forever, acting as a personal warp instead of affecting every unit on the field. The first immediately good use for the card that comes to mind is Mixed Poppo and Mother Poppo to abuse their teleport passives a little more.

Chef's Special: I don't think I'm smart enough to figure out right away who benefits the most from this, it seems better for higher HP characters and is basically a YOLO gamble to have a chance of getting all of your lost HP back if you can meet the specific Trigger condition of getting hurt and having it bring you down to 1 HP.

The Greatest Troublemaker Ever: This is going to be a MIGHTY random trolling card. It can hit allies as well, can pack 3 of them, and does 3 damage to whatever it hits. I'm having a hard time determining how to use this thing without it being incredibly risky, but I guess that is the point.

Look How Long My Arms and Legs Are Now: Clearly this caters to Trap users given how it makes everything else a higher norma level to use. Saki, Chicken, Arthur, maybe Yuki D seem like the ones most benefiting from this card.

Mousse the Thief: Can be useful against bosses besides Summer Beast and Swimming Coach since they won't hold stars much, but maybe just became a good complimentary addition to Star Devourer strats.

Coming Back Stronger: The obvious drawback of this card is that it can only be played on Norma 4, but it is a good card with straightforward effects and gives extra ATK later on for getting KO'd while this card is held. I expect this to become a new staple overall especially on Attackers.

We're Ticked Off:
This is a no brainer for anyone that uses Gift cards as part of their deck, having an extra +2 ATK when at 1 HP. Hero Kai and Tsih can be extra obnoxious with this thing.

Protection Fee: Maybe considerable on smaller boards against Star Devourer and Ropochi, but it's all luck of the draw seeing if enemies will keep landing on homes or not.

Extreme Alteration: The clear standout insane addition of the 5 point cards in coop. If the right character holds on to this and can land on 3 Terror panels, it's almost a free draw for everyone alive on the board. Dealers might start packing this but the 5 point cost means you gotta have it replace something else which will work for some Dealers but not all of them 100% of the time.

Fluffy and Fuzzy: This thing is going to go HAM with certain characters like Iru or Suguri 46B, so while expensive will be considerable for some characters that will be using card damage fairly consistently, Pilot Marc included if both versions of her hyper count as different cards for FaF.

Feel the Rush with an Energy Drink: -1 REC for all players. Obviously incredible effect but at 5 points you gotta figure out how to fit it in your deck without sacrificing something pivotal.

These cards might be the most multi-faceted cards yet, I think it will take some time to fully see where these all go. After some time I will come back and update this section.

Last is a section with pointers and miscellaneous information that will help to make things easier overall or in the long run.

When waiting for your turn, do a lap visually around the screen and check what is in everyone's hands. I don't like to order people around all the time, but sometimes people go 2-3 turns before using cards like Holy Night or Nice Jingle later in a game where holding on to them in hand has no value and playing them asap is better more often than not. There are also crucial plays that can be missed like sniping a Balloon Bully at 1HP for those not paying attention.

Once you have role(s) at level 10, take time to build and save at least 1 deck preset in Single Player --> Co-op deck preparation for all character + role combinations: This is the most time consuming thing you can do to prepare for Co-op that takes several hours and is slightly overkill since you will never realistically use every single combination possible. This is helpful however in getting used to the cards you have available in co-op and being able to understand what to put in decks better or where to find cards faster when you need to make quick adjustments later on. Since School Crashers 2022, a deck search feature was implemented so finding cards can be easier as long as you know the name of the card you are looking for if you are in a panic and can't memorize its location during deck building.

More importantly it will be a time and life saver having a preset saved for each possible combination so you always have SOMETHING ready instead of being left to the mercy of game doing automatic filler cards for your deck if you ran out of time during deck construction in an online game.

Note that the only way to have infinite time to prepare a deck for Softened(Online) Tomomo is to make a Private Multiplayer Co-op room, start a game, and then do it in there since Tomomo's role values are different in Single Player.

The other reason this is important is that you always have something ready to go and can spend more time focusing on the characters and roles your teammates are picking. Don't rush deck building and character choice and let the prep time run so you can make adjustments based on what your team picks during countdown. If you rush and ready up, you can no longer account for what picks your team is still working on.

Deck Construction is more simple if you build by bringing cards mostly that would help YOU, but leave 1-2 cards that would be good for anyone drawing them if you bring most of what you can already.

For example, Attackers and Avengers are expected to bring more damage to the table so should more often be the ones packing the cards like Hyper Accel, I'm On Fire, Big Magnum, Super All Out Mode. Guardians and Supports should usually pack a Dinner followed by more staples and smaller cards like 1-2 Rbits, Cookies, Quick Restorations. Dealers are the most versatile and don't follow a one build fits all situations rule, but should bring more cards that will help individuals such as Puddings and Rbits followed by things such as Hyper Accel, Passionate Research, and Shield Counter.

Extend should be packed by every player because REC is one of the most brutal hurdles to overcome and is simply too good to ignore avoiding the most problematic aspect of being KO'd. Rbits and Cookies are safe bets to pack if you only have 2-4 points left and have no idea what else to bring.

If you still don't have any idea what to do and want to play safe picks, below is a quick summary of typical cards to bring along with notable characters at a glance:

Attacker: Bring Hyper Accel and/or Passionate Research for 5 pts, Extend, followed with remaining filler cards.
Kae: Hard hitter and good REC for an attacker
Star Breaker: Good stats for engaging in a few fights, potentially powerful hyper
Shifu Robot, Sora Military: Always gets up after being KO'd from battle but require a bit more knowledge after Pool Party nerfs.
Marc, Kai: Starting characters

Guardian:: Bring Dinner and/or Passionate Research, Extend, followed by filler
Kyoko, Fernet: The strongest defense walls to maximize Guardian's new playstyle
Halena: A defense-oriented character with a really protective hyper and good stats for survival
Watty: One of the latest terrors in gaining passive buffs by using her high DEF stat and hyper together.
QP: Starting character

Support:: Bring Dinner and/or Passionate Research, Extend, followed by filler
Natsumi: The premier Support healer, stars for healing HP with role.
Cook: A good Support character who can zip around the board with mad high rolls later in a game if she gets her hyper.
Tequila: Able to turn damage moving 2nd in battle into higher attack rolls while playing Support
Aru: +3 EVD after Norma buffs and good support for any team
Suguri: Starting character with +3 EVD after Norma buffs

Avenger: Bring Pudding and/or Portable Pudding, Extend, followed by filler
Kiriko: Highest HP pool possible for the role alongside Flying Castle
Arthur: Solid choice all around without a bad passive
Marie Poppo: Early character/non-DLC option

Dealer: Bring Dinner, Pudding, and/or Hyper Accel, Extend, followed by filler
Yuuki: Strong hypers that will often NET EARN stars as well
Mei: Buff your team with Red and Blue gifts that +1 in all stats
Peat: Give +1HP Peat desperately needs while having a strong hyper in reserve
Kai: Starting character, amazing hyper to pass to teammates

Since Swimming Coach is a wildly different boss than usual and can be quite a pain without an organized team, I'm jotting down anything I can that seems to be something useful to use against it. It might be time to save a preset deck specifically vs this boss because of how different the dynamic is since you get more killing its mobs then trying to fight it on boss panels(or nothing in the case of Hyper difficulty). I'm all ears if someone knows something else not listed that is a good pick for the new boss.

Characters:
+ Kiriko: Her Final Surgery hyper will kill every goalpost and give 25x stars for each one killed. Absolutely nuts and a time you definitely want this hyper.

+ Iru: Her battle challenging passive is invaluable to guaranteeing a goalpost KO. Her hyper is extremely handy here no matter what enemies it hits since it will kill goalposts or weaken the tougher enemies that are difficult to damage for more than 1 damage per fight anyways.

+ Fernet: Air Strike is a good tool specifically on this boss to try and mass snipe goalposts while dealing guaranteed damage to the other bigger units too.

+ Pilot Marc: Thanks to her flexible hyper, she can kill a goalpost or power up to deal big damage to a bigger unit.

+ Sumika: Her hyper can bring back various cards sourced from the deck and used/discarded that you may need again.

+ Tequila: His hyper will generate 2 fights with the various mobs risk free.

+ Ceoreparque: Her evade passive will kill a goalpost as long as Fury isn't active. Useful in case she can't KO one when she attacks especially if playing Support.

+ Saki: This is more board dependent, but with luck of setting a Big Bang Bell and targeting a Ringer or Bully with Path Blockers(NOT Goalposts since they don't move), this may be able to hit multiple of the bigger enemies at once or possibly KO them.

+Watty: Added more than a year after Swimming Coach appeared in the game, Watty's base -3 ATK means she can have a decent chance of killing Goalposts before getting Hardened Scale stacks, and with any luck pulling off her full hyper could be really helpful to damage the ringers and bullies as well.

+Grain: Released much later after Swimming Coach dropped, Grain's hyper can absolutely decimate the floor of minions with good RNG. Him playing Dealer in this scenario or at least being supported by a Dealer will help the consistency of this strat.

* Long Distance Shot: Definitely consider packing some to snipe enemies here and there, these will probably become crucial to keep things moving along.

* Gentleman's Battle: A little more expensive than LDS, but an alternative if you really need to try and KO one goalpost while being able to challenge a bigger full HP enemy from anywhere on the off chance it can be combo'd with a big attack.

* Shield Counter: Increasingly more important as Attackers aren't as good against this boss and how powerful the mobile minions are, this has a chance of dealing multiple HP damage to the Bullies.

* Pet Snacks: A cheap -1 ATK debuff against all active enemy units in their next battle.

* Home Improvement: A really slept on card that will help draw more quickly.

* Passionate Research: Important so far for characters like Iru, Kiriko, Fernet to get their hypers faster.

* Party Time ([ConPer] GAm3CrAzY): Party Time is useful to bunch up goalposts onto one tile so that effects based on their interactions are restricted to one area on the board, but this card will become more crucial on Hyper difficulty whether or not you are going for the achievement that involves beating Swimming Coach without KO'ing a goalpost.

Mariosonicman brought something to my attention regarding the Troublemakers update, it seems that Swimming Coach is not the same since the last update. You have no chance to survive, make your time.



























(Is just a joke, at this point in time Swimming Coach was bugged to not be able to play any boss cards and had Haruo's hyper for some reason.)
