Perfection of Wisdom is a turn-based 1 vs 1 card game. You first choose one character from 5 unique ones, and each character has 30 unique cards already given. Afterwards, you just choose which card skill should be used for each turn.
This game is a mix of a fighting versus game, a 2D grid map, a card game and a turn based game. The game gimmick is simple: you just select 2 cards and 1 bonus at each turn, the turn repeats, and when you make the enemy's HP go from 1000 to 0, you win. Each game's time ends up at approximately 10~15 minutes. So you can easily play the game, but it also has deep strategic points and features psychological warfare against the opponent.
You may know the game of Rock-Paper-Scissors. This game adopts that factor as its core and also other various systems, for hardcore card gamers.
