This deck has a very simple idea - Anduin wants all the imps to himself, the greedy bugger, but he doesn't have any of his own. So why not take Illhoof's?

Ideal starting cards

Mind Vision - Good turn one play, could net you a Corruption, Soulfire or Icky Imp, but honestly even The Coin is decent for getting 3 drops out fast.

Annoy-o-Tron - Although I didn't draw any in my successful runs, the low-cost Taunt is great for slowing down face damage.

Deathlord - Taunt! Taunt is cheat, guys. Although I would note that Lil' Exorcist might be preferred if you find yourself accidentally giving your opponent Doomguards.

Mind Control Tech - Because the Icky Imps just keep coming back, Mind Control Tech will almost always hit something. If you get something great, like Kil'rek, hooray! Honestly, almost every minion target is fantastic for this.

Strategy

Steal Icky Imps with your various stealing cards - make sure you kill off a Shadow Madnessed one in order to keep it! - while using Tournament Medic to stay alive. 

Holy Nova is more in as a finisher than a board clear - your preferred board clears are Excavated Evil and Lightbomb, since they can hit more stuff, especially if combined with your Spell Damage minions.

One important note! You will likely need Power Word: Glory in order to survive the initial onslaught. Do your best to keep minions that have been Gloried alive! I had two stacked on one imp, and without it I would have lost, so be careful when board clearing!

Final note - cards like Sylvanas Windrunner and Psych-o-Tron can be replaced with earlier taunt minions if desired, I never used them in my winning attempts.
