Managed to climb to legend with this with a 60% winrate. Just a couple new cards but they are quite good. The deck can beat pirate rogue and implock with shadow word devour and most decks that get on the board early to contest your guys aren't super popular right now thanks to big priest, which doesn't necessarily have the best single big thing removal before they die (although the matchup can easily be swung in their favor with a well timed shard, or a good illuminate)

Mulligan guide is pretty simple: Cleric, divine spirit, Weblord, and crabrider are always good keeps, Shadow word devour is needed into aggro, and I'll often keep deathlord into aggro and very often into quest mage as taunt actually counters their wincon.

Edit: added shard to make the big priest matchup better.
