Hearthpwn

Well, nothing much to say about the deck. The name talks to itself pretty much. You build a wall, you win the game.
Just put Donald Trump (Varian Wrynn) on the board, and see how he build the wall, but don't forget to pass your turn instantly, because if Nozdormu appears, then you set yourself in a great spot, because your enemy has no time to react. 
On a more serious note, it's a heavy taunt deck, lacking shield slams and other removals, but compensates with many minions that can take care off the enemy threats.
Surprisingly enough, the winrate in control matchups is above 50%, and against aggro is even better.
And don't forget about your last stand, the all mighty Deathwing, helped me out to win so many games, I'm happy that i play that guy in my deck.
