I love the art and story (or what I got up to in the story), but the combat feels kind of arbitrary. Mathematically, there's not much reason to pick one card over another, since you don't have any say over whether it happens to you or your opponent. Also, maybe it's just my playing style (mostly spamming leach), but I feel like the healing outpaces the damage, so that both sides just keep building up health indefinitely.
