Seriously, how awesome would this be?
We'd have a completely separate inventory tab for cards (like crystals) and we'd be able to collect monsters as cards. I'd imagine NMs would even be able to be captured as cards.
You'd be able to decide what rules to play with when you challenge other players, including whether or not you want to play for ante or just fun. Maybe we'd even be able to acquire NPC cards via completing quests.
This would give a great indirect incentive to level higher (and acquire better cards from monsters).
