This is a super fun deck! I haven't won much with it, but it's still really fun to play. It's all about using small AOE to damage your minions that benefit from being damaged. (For example, when your Unstable Ghoul dies it triggers your Raging Worgen, Acolyte of Pain, Gurubashi, etc)
Wild Pyromancer + Commanding Shout is a great combo that has saved me a few times.
If you don't have all of these cards Inner Rage, or other Enrage minions are good fillers.
Grommash or Ragnaros would fit well if you have them! Molten Giant is also an option, but I haven't tested it.
