This would be so awesome. Plus it's not like they have to let you have all 12 cards be the Balance or whatever. They could say max 4 of any card type. I do like the idea though of having dual purpose cards though. Like for example balance, 10% damage increase, but if used on an enemy 10% damage reduction. Arrow does whatever speed increase on the party member, but on the enemy it does a Slow effect. Bole increases the party member defense, but on an enemy it reduces their physical. Ewer refreshes MP, but if used on an enemy it reduces their magic defense. That would alone make things more interesting as at least when you pull Ewer at the start of a battle you have a use for it.
