Hearthpwn

The theme of this deck is to hit your opponent in the face with massively buffed minions, like a 36/36 Lightspawn or a 44/44 Mogu'shan Warden.  Alternatively, hit him in the face with his own minions thanks to Thoughtsteal.

As should be obvious, the midrange goal is a huge minion that you can one-shot with.  It's also possible to play rush with an early advantageous draw, such as Lightwell + Power Word Shield/Divine Spirit + Inner Fire, giving you a 7 or 10 attack minion that heals itself.

Lack of Taunt is a weakness, but you always want minions on the board that your opponent can't afford not to kill. If it goes to endgame, the Mind Control is there to stop a legendary draw or an annoying Taunt minion that you need to get past.
