I love the idea, it's fresh! But one things I read in a previous post is that you wouldn't be able to trade cards? I think that should be a definite feature, In every trading card game out there, trading is essential in fact its in the name.. I don't think it should be left out. As far as tetra masters you lose the game you lose a card? Eh it was a cool aspect, but if you lost it sucked bad.

Also I remember in VIII you could get cards from bosses? (may be mistaken), this would be pretty cool, and a good reason to go back to old content as long as the drop rate isn't terrible
