Hearthpwn

So this is obviously a pretty expensive deck; an obscene level that for most people I wouldn't recommend crafting it. If you already have all or most of the cards, then it is pretty nuts.

Piñata + Ziliax is an insane recovery / heal - you get a LOT of value through bone drake / / piñata / twilights call / cube,  Zola + Reno Jackson are insane heals, Duskbreaker, Dragon potion, Primordial drake are some aoes...

It is a well-rounded midrange deck with a lot of defensive taunts, AOE, heals - you want to prioritize getting your quest done vs agro and prioritize high value vs control builds. 

Umbra will usually be killed turn you place her - only rarely do you get to combo her on board with a cube or what not, but if she does survive 1 turn you get to do shenanigans.

N'Zoth is the finisher similar to Guldan demon res, Dragoncaller Alanda, or Chef Nomi.

Try it out, ask me if you are curious about any substitutes.
