Mulligans
This deck’s main goal is to control the board and utilize the Deathrattles of your minions to the best: shuffling as many Plush Bears into your deck as possible with Ticket Master, summoning multiple 7-cost minions with Cursed Vagrant or Plagued Protodrake, etc. Necrium Vial, Baron Rivendare, Grand Empress Shek’zara and Stowaway are all cards which can help you witht that.
