Though you can't customize your own deck, it is worth the $10. The gameplay is down pack and the AI is wonderful.

This game only has one flaw, but that flaw can be seen as a need for the core of this game. The flaw (or maybe not a flaw at all) is that you can't customize your decks the way you see fit. Though most people see the flaw in this, I see there is a balance in the decks as well as keeping people from making ridiculous decks that win in 1 to 4 turns. I am glad they kept it basic. I personally can't wait to see some downloadable decks to come online. The unlockable cards are nice and you can edit them out or in. I wished though you could take out some of the core cards as well. I ran with the green deck to start off, but I think I could have done better to drop the 6\4 wurms.
That may be my biggest problem with the game. I would also have liked to play the co-op campaign online with some of my friends or at least have the ability to choose some of my opponents other then hoping that my friends can hopefully reach my game before someone else takes their place.
