Genn Handlock?

Warlock’s best removals are even, which fits Genn okay. . Twilight Drake and Mountain Giant are really useful (with Genn you can even Mountain Giant on turn 3 with coin which is kinda crazy). I might consider adding more “classic” handlock cards like Ancient Watcher or Defender of Argus, which go along with getting high stat minions out. It definitely suffers from a lack of Molten Giants, but it could be interesting. Hooked Reaver in particular looks good, since you’ll be losing a lot of health and only have the spellstone and DK to get some back. 

Other options include Bonemare, which is probably a better fit in this deck than the Lich King (you don’t want his DK cards filling up your hand and milling you), Gnomeferatu, and whatever even cost cards the Witchwood gives us.
