What is more important than anything else is match talent. Because this cannot be changed.
The most important thing is Strategy Points (SP). And among them, there are those that are efficient. The rest are just options.
We've compiled a few of the most important features.

Among these, even Hell difficulty is not difficult with only “Energy Efficiency” and “Inspiration”.




1. Invoker - very powerful
1)Never - Mihawk, Babe, BaJie
2)Synergy - Field Dealing(LADY, QUBE, Enedi, justice...), Shuffler(Felyn), Buffer(Cubey, hass, kid), Use only 1 card
*preserve DeepSpace Missile
*Versatility Card : total - 2 cost
*Warm Up x 4 : - 4 SP


2. Charge Horn
1)Never - none
2)Synergy - Use only 1(LAN, Ada, DeepSpace, buff warmup, SP-1 coin, Versatility card)
*Even though DeepSpace Missile missiles are disposable, they are not deducted.
*Versatility Card : total - 1 cost
*Warm Up x 4 : - 4 SP

3. Imitation Master - Use only 1
1)Piggy bank - Not tested
2)Quick decision - all card cost -1

The following is an introduction to the characters actually used in the game. In fact, there are some problems with playing the game without understanding it well. I know what's good, but I haven't verified where to place it or use all the characters. The introduction at the top contains the results of trial and error.

Top
Match Trait - now "Instructer" -> future "Energy Efficiency" or "ZEN"
*I play most of my cards in jungle and bottom. According to experience ZEN appears to be usable in TOP, where cards are rarely used, under the condition of using the skill only once per turn, but I have not been able to test it. Even if you use the card twice in one turn, you will still break even. Actually, I prepared a character to test, but since a character equipped with energy efficiency came out, the character limit was 7, so I deleted it.
Match Trait - now "Instructer" -> future "Early Bird Ticket"
Reduces enemy preemptive attacks. Additionally, this trait can only be obtained by tops and subs.

JUNGLE
Match Trait - now "Energy Efficiency" -> future "Eager to Fight"
In the beginning, sometimes I feel disappointed with the first round.
CARD - I wanted an "Surprise Assault" card, but it doesn't appear for this character.

MID
Match Trait - now "Charge Horn" -> future "Invoker"
Match Trait - now "Charge Horn" -> future "Energy Efficiency"
CARD - now "Watch This!" -> future "Versatility"

BOT
Match Trait - now "Invoker" -> future "Charge Horn"
I think "Invoker" is the best option as some cards don't have the charging horn working properly.

SUP
CARD - I wanted an "Surprise Assault" card, but it doesn't appear for this character.

※I'm not very confident in English, so I used a machine translator.
The translation was a mess so I edited it a bit.

Starting with the first turn, the enemies attacked Gilis in the center with four people through the portal.
Gillis' stats were high, so he lasted until turn 3 due to misses (Gillis also missed turn 2), but with the anger he had built up, he caught the Lan with one hit on turn 3 (reverse first kill) and died (remain 4 vs 4) .
When it's my turn, I use the Energy Efficiency trait (SP+2), use 2 books worth 0SP (SP+2), which give +1 strategy points and cards each, and then use Deep Space's "Missile" for free. Attacked two people gathered together. I used "Look at this" with 1 SP and moved the Zealot one space with a card worth 0 SP (see the shrinking yellow circle). Then, I used Zealot's "Claw", which became SP0, to move 2 squares, and used Acedia's "Eureka" to make SP-5, and used Wokong's "Dive Attack" by paying SP1.
When I caught 2 out of 3 people, my SP increased to +4 by "Watch this!", and my SP became 14 (=8+2+2-2+4). Zealot's SP4 initation card caught the other person, making the score 4:1 (SP10). I had a lot of SP left, so I used the shuffle given by "Watch this!" and the Zealot's scratch came out again. There are only 2 distance from the enemy supporter at the bottom right. But then “Watch this” came out again? After using "Watch this" again (SP-2), and then charging in with a scratch (SP-1), the three of us eliminated the enemy supporter using Zealot's initiation. By “watch this,” SP again increased to +4 and a shuffle card came in, and the remaining SP became 10-2-1-4+4=7.

Use Deep Space's "Precision Air Strike" and "Missile" once each on 5 revived enemies at once, they will lose 1/3 to 1/2 of HP.

A few turns later, we met again at the tower. There are two people at the bottom, so out of courtesy, use the missile once. After moving Gillis one space to the right with Gillis' "Hypnosis", use "Eureka" again to kill 3 people(4 vs 3) using SP1 in the fascinating invasion that comes out as a combo.

Oh, Ninja... he will die soon.

Lan flew in with an assassination and Bottom was surrounded by 4 enemies and was annihilated. So I sent Gillis to the bottom (SP-2) and used “Enchanting Invasion.” Together with Zealot, I killed two enemies with low HP. Still, because it was a championship match, there were 3 deaths.

Even though it is a champion match, the dragon has 2 turns left and the enemy's SP is 1. I am 8. Dragon is the bottom, so let’s harass the bottom. Since there are 2 of them, them with a big, beautiful missile, shooting the monkey. with Gillies' Overwatch, then changing the versaility card to initiation to beat them 3:2. Gillies had 2 kills. Automatically the blue dragon is mine.

Before I knew it, the tower with the least activity was breaking the inner tower. As soon as the enemies are revived, they try to attack Wukong with monkeys, but Gillis is looking at the monkeys? It became 2:3, not 1:3. Wukong is a tank and Gillis is invincible on turn 1. Gillis deleted Lan with 2700 damage. The enemies used several attack cards to try to eliminate the bleedling Wokong, but the tank did not die.

And then it's my turn again. Soon it's a messenger, I could proceed steadily to win, but the game is too easy and not fun, and the bleedling Ninja is badguy, so I decided to stop it. Energy efficiency and inspiration cooldown are back. When I use "energy efficiency", “watch this” came out again. I immediately used my inspiration to decrease cost 1 and use it. Hit the ninja one more time with a probe attack, and delete the supporter with a dive attack from Wokong, who has become SP1. Then jump to the pirate with Zealot's claw and run initiation. Gillis, who is invincible in turn 1, deletes it. Since there is one missile left, I think I can delete the bleedling ninja.

Because it always hits, the ninja dies right away... and my SP is still 8. When does my turn end? Since we have a lot of SP left, let's catch the monkey (actually, it's natural to win, so we'll just hang out in the tower and have fun). Shuffle once, scratch with Zealot's claw, and perform initiation. I wanted to play 1:1 with the monkey in the tower, but Gillies was still watching the monkey (damn, it wasn't even the 10th round of Overwatch yet). Even the monkey is deleted... I have 2 SP left, but there's nothing to do, so I turn it around. The bottom's HP was almost half, but it did not return. This is because my SP is more than that of the enemy.

It's a messenger battle. As you can see, I have an average of 2000 gold. If it were a human, he would have surrendered, but the AI ​​accepts the messenger to see if his fighting spirit has not died yet. Gillies easily scored 2 kills.

Even after the messenger battle is over, it's my turn again because I have a lot of SP. Meanwhile, the bottom destroyed the inner tower with half its HP. “Watch this” came again. I think I can gain more than 10 SP in one game just with this card. Shuffle is a bonus. If I do well, I think I can finish it this time. Let's calculate.
Missile -1, Dive Attack -6, Look at this -2 = -9
Look at this +4
Showdown -4 = 0
The game is over. Let's go for a deserved victory. After using “missiles,” I used “dive attack.” Deep Space, who recived all red/blue buff, eliminated enemy by scoring 3 kills with 3 consecutive critical hits.

It's also an all-kill, but you can use a decisive battle. The game is over.

Perhaps because it was my turn later, I had as many as 3 deaths. Let's reflect

Partial kills didn't even count. In one game, the enemy was annihilated three times.

Below are the first turns and results of the second game of the Premier League final.

Below are the first turns and results of the third game of the Premier League final.

Of course, it wasn't this overwhelming from the beginning. However, "E. Efficiency" and "U. Inspiration" are enough for even beginners to play on Hell difficulty, and once you get used to SP counting and the card set is correct, there is actually no need for even that.
In fact, even without knowing anything, I played a game or two on normal difficulty and found it too easy, so I switched to hard difficulty, but it was also too easy, so I immediately changed the game to highest difficulty. Still, the highest number of deaths was 7 deaths (of course, I had about 20 kills), so it wasn't difficult. From the beginning to the Premier League, the enemy reached the nexus in probably one game that I remember.

(Content cut above added)

SP is a skill in the game, and Initiation is the same as the ultimate. If you hit the skill and ultimate almost every time, you will win the game even if you are pushed out of the line (even if you have low stats). The reality is that if the abilities become similar, not even one tower will be lost. Honestly, in order to play a game worth playing against AI, I think you need to restrict yourself by excluding SP sets altogether, or using all SP possible in a given round without SP counting.
I played LoL for a bit and quit (because I like War 3 Chaos and Dota), Speaking from experience with Blizzard's Hero's Storm, the computer's skill level seems to be at a low rank of Silver or Bronze. There is a need to greatly increase the difficulty level of AI. For reference, I'm about gold or platinum. My hands and eyes were slow, so I couldn't go up any further. This is easier. In order to reach Hell difficulty, the AI ​​difficulty seems to have to be at Master Rank level.
At Platinum level, you can even win Master if you're lucky.

※There is no need like "growth". Because if you win a few teamfights, the game is over.
Even tanks are no exception. Heroes should use specializations such as HP, which automatically improves with level, rather than improving cards which cost SP to increase stats other than attack. Wukong's HP +300(+400) card is also not used unless there is SP left. So I think I made the wrong choice to improve Wukong's HP increase card. Even though Wokong's attack power increases according to his maximum HP, it is a waste to use SP because he is not a dealer. He cannot capture a hero within 3 turns.
