Hearthpwn

I've never seen big priest in this format, and it's very effective... past turn 6. In fact if you have a good start then it's really hard to lose after. In aggro matchup the best way to win is stall until you can play shadow essence, if you land a Dragon Hatcher or one of the defensive minions then you've likely won, unless they have enough burst to finish you off. So it requires a bit of luck and a good mulligan. In control matchup I find this deck rarely loses as long as you have spellstone in hand early, make sure to use the Malygos spirit lash combo or at least be aware of it. The decks biggest weaknesses are aggro especially odd pali and zoolock, and big taunt druid is a really tricky matchup and very close often (try to get to fatigue). You make some amazing boards and get loads off end of turn value off ysera and the lich king. Consider adding in the lady in white to make some good memes?
