I just have to say that I'm tired of reading people talking bad about this game. OK, the game is hard, but that doesn't make it the worst game, it's just hard. The AI is perfectly balanced to me, you just need to know how handle it, and doing so took me about 10 minutes, not weeks as some guys are complaining about. Just try build your deck the way it's better against the AI,mainly the hard one, wich I can make sure it's not the same one used against those easy peasy levels.
