This deck is by far my most successful Warlock deck. It relies on heavy board control by summoning ridiculous amounts of 1/1s and using them to either buff up the Frostwolf Warlord or sacrificing them to put out double Volcanic Drakes (Twisting Nether combo with this owns).
We also have some Void Terror combos with the Power Overwhelming and Sylvanas Windrunner. Power Overwhelming in general is really good with some disposable 1/1 minions and Shadowflame.
We got our taunts by using the Voidwalker and the Sludge Belchers, the Blackwing Corruptors are some nice damage cards.
The two Siphon Souls are our direct removal and heal.
One Sea Giant and one Raid Leader both give this deck some good variation. The Faerie Dragon acts as a trigger for the Blackwing Corruptors and give us an annoying early game minion.
