Cursed Blade and Flame Imp 

Loatheb and Millhouse Manastorm 

I would say Wild Pyromancer + Unleash the Hounds

UtH serves as an AoE for hunter (according to Blizzard) and all classes besides hunter can combine their Aoe with Wild Pyro

Rogue with weapon + Rogue HP :(

Quick shot/Core rager/Brave Archer + Lock and Load.

Wild Pyromancer on board (e.g. from Shredder) and Force of Nature + Savage Roar.

Chillmaw + dragons in Grim Patron warrior Kappa

 but Djinni says "on friendly minion" how could that work when you target an enemy minion?

Auchenai Soulpriest + Reno Jackson

Brann Bronzebeard + Loatheb + Lorewalker Cho OR Millhouse Manastorm

Nourish and draw cards + Astral Communion

Millhouse Manastorm + Spellslinger or Jungle moonkin

With Thaurissen discounts: Twisting Nether + Anima Golem

Brann Bronzebeard + Pit Lord

Lifecoach + Control Warrior + Nozdormu 

inspire mechanic + rogue hero power

Majordomo executus + hearthstone.

I forget who said it but I think it's definitely auchenai and mistress of pain. That will kill you from full health no matter what, while things like auchenai + Reno/tree of life can be survived with things like armor. Plus, Reno and auchenai can just be played as an attempt to regain tempo of your deck still has duplicates.

Void Crusher and nothing.
