Mulligans
General Mulligans
Only keep Prep with a perfect hand.
Complete the quest, and use the reward to stall or play agressive if your against a slow deck. until you can Leeroy Jenkins + Preparation Shadow of Death +Shadowstep combo him.
Next turn you could do Leeroy Jenkins and Shadow of Death him again.
After that either Gadgetzan Auctioneer or Heistbaron Togwaggle those Shadows out of your deck.
A version without the quest might be better, but this seems more fun. Tess might be an option for this deck, but atm I had to cut her. She might replace Captain Greenskin though.
