This a pretty cool game! I wouldn't have considered doing an auto-battler, but I think this works pretty well. The characters look good, and the cards all have interesting and reasonably significant effects. However, I do wish the game was harder. The 5-drop card is extremely powerful, as well as the HP buffing 1-drop. Something like a cooldown, changing movement speeds, or even just adding more cards to make the 5-drop rarer could work.
