Not a game for everyone, but a must try for most.
If you used to play Magic The Gathering then you should be able to pretty much to pick up the game and play it without to much worry. If you need a refresher course or have never played this game does offer a tutorial and plenty of helpful tips to aid you along the way.
The gameplay can be addictive and challenging, but also offers unlockables as a reward for progressing through the game. There is also online co-op for 2 players, and vs modes where you can put your customizable decks to the test.
The graphics are pretty decent considering it's a card game. You'll see some nice artwork on the cards, but don't expect to see monsters hopping out of them and fighting each other. "Although I think that would be entertaining". The soundtrack is pretty basic, but it also isn't real noticeable so it's easy to ignore. "Even easier to turn off and put on your own music".
All and all I think the game is worth the 800 MS points. With several single player modes and the online play this game should offer plenty to keep you busy without the hassles of using the real cards. I also think that this will be a game that gets DLC off and on. "My guess would be new decks and challenges".
That's my .02 MS Points
