Okay, so I am new to this game but here is what I am noticing. I may be unobservant, but I have found no way to have two independent decks at a time of your own creation. Alright, a few quick suggestions. First off, there should be some kind of market and or auction house where you can sell and buy and trade cards with other people. Second, the energy should have a higher limit (I know that i in other comment). Third, I think that it should be easier to get DP. Yes I know it comes occasionally in different ways, but maybe add a few more so we can have higher frequency in gaining DP. Finally, I've heard some complaints about the inability to play your friend without his deck being controlled by AI. Alright, I'm done.
