I dont think trading would make a difference. Covi, thats an odd statement considering that if you trade you will have the same amount of cards, just a different amount. Besides you cant use the same card in the same deck.
I thought this was a very nice game. Like dietsnapple said, the art work was lovely. I loved how there wasn't a basic 3 move set with maybe 2 combos. If there was a story mode, trust me this game would be even more amazing. 4/5 I dont get why people say its boring or it sucks.
