12-0 Battlecry Control Priest

1st Passive: All Together Now

2st Passive: Rally the Troops

This deck was the deck that got me my first 12-0 with Priest, working with the amazing Battlecry Treasures. From my experience, you simply can outvalue almost any deck from the insane amount of card draw that you have from healing and Rally the Troops. From my experience, it was best to always take the best card bucket over not taking more cards, for you don't want to run out of cards, and even on my last game I was down to my last 12 cards after drawing over 40. 

You most likely will lose to any Combo style deck, but as long as the game lasts more than 3-4 turns, you can generally pull a win eventually.
