If we keep the idea of an Infinite mod, the game need to be separated between round, for ajusting basic's card, maybe between round, player can afford multiple thing, like the player have 1 spare time, he can go to a shop where you can take one more card in your deck with some effect, or maybe take a object wich give another passive effect, maybe the player can choose to train during spare time, to gain a power or more size only for the next round. Maybe rounds can change, like the opponent having card bough in the spare time, or the place where the fight take in, making some fun effect
