Hearthpwn

Evolve deck with some late game Jade potential. Dropped Doppelgangster as a common package to favour faster jade growth. Also includes our good old friend Loatheb for a mid-to-late game board saver and Shudderwock for a refill and lockdown (if you already played Loatheb) in the very late game.

Totemic Smash is here to speed up your Thing from Below cost reduction. So is EVIL Totem, also for the tokens it generates. If left uncontrolled, it will run out of control easily.

Rummaging Kobold is here for a free weapon and nice evolve token. If you happen to have Brann Bronzebeard in hand / play, he can get you two weapons as well as summon you two golems on the same turn if you can play a weapon (or two) as well. It's a huge board swing in the mid game.

Substitutes

If you dont have Loatheb and Shudderwock, include 2 x Mogu Fleshshaper. It will push your game to more of a mid/late than very late game, but they're great early game control and evolve very well :)

It's possible to go all out on battlecry quest shaman as well, I would drop a Totemic Smash or Brann Bronzebeard for Corrupt the Waters.
