Typical Quest, Reno, N'Zoth priest. With Shadowform.
The idea is to hit Shadowform with Shadow visions, or Kabal Courier. Empowered with Raza gives you some pretty good ping. Loads of healing with Amara, Reno and Priest of the Feast. You have 7 deathrattles but often need far less with resurrect effects from Resurrect, Onyx Bishop and Kazakus potion, as well as N'Zoth. Classic priest removal and clears, value through Medivh, Kazakus and your opponents cards. Screw up combo decks and stall out aggro decks with Deathlord(s).
Cards that I'd cut first: Cleric and Vol'jin.
Cards I'd add: Brann.
