Hearthpwn

I've won about 30 games with this deck and lost very few. Mostly I ignore the opponent and go face; however, I do kill Sorcerer's Apprentice, preferably using Light's Justice(from Muster for Battle) to keep as many recruits alive as possible.

In a typical game I play something like this:
Round 1: Lost in the Jungle
Round 2: The Silver Hand
Round 3: Muster for Battle
Round 4: The Coin -> Level Up! or The Silver Hand / Unstable Portal
Round 5: Level Up!

Board clears can be pretty detrimental, but then you still have the Level Up! that wasn't used, and your opponent probably knows that, so that's a constant threat.
