Hearthpwn

This deck comes with good defensive with Humongous Razorleaf and
Imp Gang Boss which will stop small attackers.You can use Mortal Coil, Stubborn Gastropod, Volatile Elemental to kill a single target as well. Flame Imp and Dark Peddler can be used to either offense or defense early game.

The main offensive troops areVoid Terror and Ravenous Pterrordax. You will need to feed them with a small imp or Devilsaur Egg.
Brann Bronzebeard will double these effects to produce gigantic monsters
with charge effect from the brawl.

Dread Infernal can be a good finisher late game. He will clear your opponent
board with 1 damage to all minions and 1 to each player. Then attack at the face for 6 damages.  If you have Power Overwhelming the damage will be rised up to 10 damages at this step. Lastly, you may play Void Terror to consume the infernal and become 13/13 or larger run toward the face again. The total damage for only this turn will be 1+10+13 = 24.

Everyone can build this deck. I hope you enjoy it.
