Hearthpwn

Very Satisfying dragon Priest deck. Incorporates some strong turns and heavily valued minions

Playing on curve from 1-6 is highly possible and strong.

it has some solid taunts for fighting off aggro, double shadow word pain for those doomsayers and councilmen

3 ways of removing big minions in death/entomb

3 mass aoes to deal with huge board pressure(token pally right now and zoo are everywhere)

has a good line of death rattles leaving your n'zoth one of strongest next to pally's

^which you can even steal their tirion and make their n'zoth pretty bad

very long sustain in alchemist and justicar

And as a tip to the iceberg, Ysera is there just as an out in the hyper late game against some control matchups where you waste all of their removals leaving it near impossible to easily get rid of her.
