Well, it is good cards game, with about 2000 different cards, you have infinite combinations to create a good fighting deck (but your online challengers have the same possibility!). It is what I like in it, when you're beginning a fight (against an human online), you never know if you'll win or loose. I just can't stand the disconnecting ones just before loosing, but it seems that it is as in other things, sometimes no fair-play...
I advice you to try it, it's pretty good (and addictive, too!) if even you're liking card games
