Hearthpwn

When compared to cubelock, this deck always has a play on turn 4, with Twilight Drake, Mountain Giant and Voidcaller. Being able to Life Tap for only 1 mana is massive, as it allows you to tap and play Doomsayer or Kanrethad Ebonlocke on turn 3 followed up by a big turn 4.

Other synergy with 1 mana Life Tap:Turn 3 Mountain Giant with The Coin.

The deck plays much more aggressively than cubelock. You can often play massive minions one after another starting turn 4. Basically play the most threatening minion each turn and pressure face as much as possible. At some point you have too much pressure and the opponent runs out of removal. I have literally been able to set up lethal 5 turns in a row against a rogue after having my board cleared with multiple Zephrys the Great.
