Climbing in ladder with 60+ WR on high ranks (currently rank 1, about 10 hours gaming)
Super heavy defensive version of Mecha'thun Warlock, good against all meta decks.
Easy win: Control warrior, Quest druid, Resurrect priest
Good: Quest shaman, Murloc shaman, Tempo rogue, hunters, paladins etc
Very bad: any Hakkar decks, OTK Paladin (slow draw)
