Hearthpwn

Kooky Chemist, Crazed Alchemist, and Shadow Word: Pain for destroying the Bone Spikes...or Mind Control to use it for yourself. If you can't kill them, Silence is the next best thing.

Vicious Fledgling, Daring Reporter, Lightspawn, and Free From Amber provide potential minions to buff for a 30 damage turn. Mindbreaker can provide a multiple turn kill if it can be kept alive. (I didn't use Mind Breaker when I did it so I actually don't know for certain if that works on bosses).

Acidic Swamp Ooze can counter his weapon and a few other cards included like taunts for defense and some hoarders for card draw.

**A lot of comments I see are saying that Mindbreaker does not work in PVE so that card can be replaced. Cabal Shadow Priest is not included because this deck is based on my collection and I don't have that card. It is useful if you are trying to win the game with the Bone Spikes, but that is not what this deck was originally made for. In that case, a Mirage Caller can be a very useful inclusion as well.

Also, I updated the description with card links for convenience.
