Mulligans
This is a solid Control Warlock deck . It counters all aggro Baku Decks with Rotten Applebaum, Dread Infernal, Lord Godfrey, Alexstrasza ,Despicable Dreadlord, Hooked Reaver, Hellfire and Control and Combo decks ( like Battlecry Shaman ) with cards like Gnomeferatu and Rin, the First Disciple
TIP: When you play versus cubelock or battlecry shaman try to mulligan for Rin, the First Disciple and never play it on curve . The best play is to play it on 7 mana turn and destroy immediately with Dark Pact . You must do this in order to play around Hex or Spellbreaker becuase in these match ups Rin, the First Disciple is your main win condition.
