I love the card ideas, but the only complaint I have is the confusion between "characters" and "monsters" or "creatures." Characters makes me think of a player, such as an AI or someone in PvP, or a pixel avatar that someone would use in an online game. Monsters that are summoned are the last things I think of when I hear the word. It's not really confusing me, since I know what you mean, but it's quite annoying when my mind WANTS to read "creature" on the cards, but instead it says "character" and it just doesn't make sense to me. =/
