For collecting all cards, I recommend referring to the Official Iris and the Giant Wiki[irisandthegiant.fandom.com]. You can go to the card you need, and easily find what monster drops it, and from there, it will tell you where to find said monster.

Also, note that for the Wide Mouth achievement, you only need to collect 50/60 cards.

This is the first time in my life to write a guide, please correct me if I make any mistakes. This strategy is mainly aimed at the big mouth in all achievements, that is, the method of obtaining all cards. Why did I add a pseudonym to the title? Because as of 2020/3/8 I played all achievements, even if I lack a card, I can still get all achievements. So it is mainly aimed at how to get a card other than one. In addition, I named the monsters at will, and did not follow the official monster names. The last point is about how to encounter monsters on which floor and get the designated card, I think. . . I'm lazy.

No matter what the size is, the sword can be taken from the stealing card used by the little skeleton below in addition to the treasure chest.





In addition to the treasure chests, bows and arrows can also be stolen from ghost cats and bow cats. As for how the ghost cat stole the bow and arrow, of course it was stuck with a sickle.







In addition to the dagger in the treasure chest, it can also be stolen from the dagger snake.





In addition to taking the axe from the treasure chest, it can also be stolen from the tauren.





In addition to the hooks in the treasure chest (seems like you want to bring memories or fantasy friends), you can also steal them from the pirate meow.





As a stealing card, traps can be obtained in three ways: treasure chests, trap pigs, and traps placed on the ground. (But the trap will be triggered automatically when it reaches the first row, so you can only use the trap card to steal the trap on the ground, in the infinite doll)





The sickle is also a stealing card, and it should be stolen from the sickle snake. (This card has a special purpose)





The stone axe seemed to be stolen from the stone cow.





The rock card can only be stolen from the one-eyed man when he is about to hit you with a rock.





Fire dragon, as a common card, can be obtained from treasure chests and monsters.







In addition to getting the bomb from the treasure chest (seems like you need to bring memories or fantasy friends), you can also touch it from the bomb snake.





Raiden cards can also be obtained through treasure chests (with memories or fantasy friends) or monsters.





Waves can be obtained from treasure chests (with memories or fantasy friends) or from monsters.





The stone eye card can not only be licked from the monster, but also can be found from the treasure chest with fantasy friends. (Updated today, thanks to a classmate for leaving a message)





In addition to the shield card in the treasure chest, the monster can also be obtained (I didn’t expect it)





The mirror card looks like it is in a treasure chest. As long as the monster holding the mirror in the hand can steal it (bottle, snake, and skeleton will all appear with the mirror, when stealing them, they will be judged as a mirror first, even if they are blown away by waves)



In addition to the treasure chest (crystal treasure chest), the sword dance card can also be snatched from the monster.





Snake cards can only be stolen from the snakes at the 12th level and 2nd stage. (Only the snake root is kept in the illustrated book, bad review)





Whip cards can be obtained from treasure chests (requires bringing memories or fantasy friends) or monsters.





No, although this card is marked with a star on the upper right, people who have cleared the level several times know that the last few layers are fixed monsters, so they are listed as ordinary monsters. Of course you can only steal from them.





Tears card, the only curse card in the whole card, can wait for three skeletons to give you, of course, you have to steal from the sad skeleton.

The treasure chest card is derived from the treasure chest monster, but it seems that stealing the incomplete treasure chest may also be effective? (I haven't tried it anyway)





The golden sword comes from the golden skeleton, a very rare monster. In my 30 hours of play, I only saw it 5 times. And I haven't noticed the first 4 times, so you must observe carefully.





Not all sheep are called golden sheep, and not all treasure chest rooms will have golden sheep, one of the rare monsters. When you encounter it, shuffle the cards and pay, I don't know if it will run away or attack.





Isn't it good to be a good cat, do you have to come out to be a pirate? The pirate hook comes from the pirate meow (look at the picture and talk, haha)





The giant axe is matched with the giant cow (because you can get a very good transition card in the early stage, it is best to steal it), everyone should meet the BOSS.





The good cat feels Archer with a golden bow?





You think what you stole is the dagger in my hand, you are wrong, it is the invisible floor mirror in my hand (independent game, the illustration book is not very good in this aspect, please forgive me)





The difference between me and my brother is-I am more like a stone





Now that the more you look at this picture book, the more ugly you feel, that Queen Medusa has become a giant stone-eyed monster? Here is the specific method for obtaining the Medusa Queen Card. Since Medusa does not eat single cards, it has and can only use sickle cards to steal Medusa's cards. By the way, Queen Medusa should be at 10C and have to enter from the 9th floor.





Gourmet Cards can only be obtained from hounds and stolen after breaking the armor.





The source of the golden shield is the giant flying pig.





The Summoning Skull Card comes from Asuka.





The forging card comes from the wild boar that has been on the anvil.





The bouncing trap was taken from the big hedgehog.





Finally, the big skull is the end of this chapter.

To be honest, I really didn't expect that things inherent in the scene could be stolen, hahaha. Crystal cards are obtained with stealing cards just before they are broken.

There are also bomb traps that are stolen with long-range cards in the later stage.



For the rest that don't have much gold content, just look at the pictures and find the corresponding things. ,



Of course, there are also cards that can only be obtained when leveling up, and have no gold content, so they are listed together.







It should be noted here that the bullet time card can be obtained through upgrading, or it can be obtained from the mouse





Finally, there are two special cards, the former needs to bring memories, and the latter needs to bring fantasy friends.

Finally, I will post the illustrations I have collected for your reference.
