Hearthpwn

Overview:
Outlast him, until he dies from fatigue, or you can summon the Four Horsemen with Uther of the Ebon Blade.



Mulligan:
Scorp-o-matic is absolutely vital, you must have it to survive the first Bone Spike. You can also look for low cost taunts: Righteous Protector, Tar Creeper, Stonehill Defender and Consecration. Toss back Wickerflame Burnbristle, he's more useful later on if you need healing, and also is another proc for Corpsetaker.

Early Game:
Play Righteous Protector, Tar Creeper and Stonehill Defender, and supplement it with your hero power. The Silver Hand Recruits will likely die to Bone Storm, but if not, they can help chip away at enemies or finish them off.

On turn 3 or 4, he will play the first Bone Spike, so respond with Scorp-o-matic.

Mid Game:
Save the Mossy Horrors and second Scorp-o-matic for the rest of the Bone Spikes and start looking for the Acidic Swamp Ooze to counter his weapon. Continue to heal: Lightforged Blessing is great here, and play taunts (Zilliax can magnetize to Scorp-o-matic for extra damage and healing).

As you cement the lead, play Tirion Fordring and help clear with Ashbringer. Or if, you have Uther of the Ebon Blade, wait to play him until you break Grave Vengeance.

Late Game:
At this point, you have total control with the taunts, Tirion Fordring, Ashbringer and Ragnaros, Lightlord. Either one of two things will happen: he'll die from fatigue and face damage, or the Four Horsemen will be summoned. Either way, it's game.
