Hearthpwn

This is the tank priest build I used to beat Slitherspear, What you want to do is hard mulligan for Northshire Cleric and draw up a few cards, you don't want to remove his minions if you can avoid it. What you want to do is just tank up using power word glory and lightwells until he has a board full of hungry naga and silence them all with mass dispel, then he has a board that only can do 7 damage (in the most optimal case) and you just heal constantly until you draw both divine spirits and inner fire. 

Tips -
 - Holy smite is soley for removing Ice ragers, save it for them. 
 - Shadow word Pain is for removing water elementals, save it for them. 
 - If you have mass dispel and silence in your hand you might want to silence some of the bigger naga to save you some HP while you wait for his board to fill up 
 - Save Shadow word Death for the 5/7 taunt minions, that damage needs to be removed. 
 - Make sure you play Power word Glory AFTER you silence his minions, if you want to play it early to keep you alive that's fine but just realize that you will lose the effect after mass dispel. 
- PRAY TO GOD he doesn't draw a FUCKING SEA REAVER after you silence his stuff, that is really the only weakness to this strategy, if it happens the turn after you silence his stuff you're basically fucked unless you already have the combo materials. 
- Again, the goal of this deck is to neutralize his board state while at the same time negating his hero power, that's why this deck doesn't run clears. I had a version before this one with doomsayers and lightbombs and I realized I never wanted to use them because I wasn't going to be able to deal with is board a few turns after. 


This deck took me 2-3 tries to beat him with, if you don't get northshire/power word shield soon you might want to concede and try again. Good Luck!
