Wow, I just downloaded this game and it's blown me away. I love the play style of the game, managing the turn by turn mana cost and playing just the right card at the perfect time.Even the "freemium" parts of the game are satisfying since a little bit of effort can nab you gold for almost anything. The only complaint I would have with this game at all is that the game times can draw out pretty long for a mobile game, and leaving and coming back to the game could result in a loss quite easily. Otherwise I love the way this game is, I think I'll spend quite some time trying this out. So far I've unlocked every character and finished first arena playthrough.
