Oaklock

A control/fatigue warlock variant built around Master Oakheart. The dream Oakheart package is Tar Creeper for 1, Deathlord for 2, and Voidlord for 3. The only other potential target for 1 is a single Tar Creeper which is still a solid option. Use your spells and Doomsayers to keep your opponent's board clear until you can find and cast Oakheart. Gul'dan is for getting double milage out of your Voidlords and will even sometimes bring back Dreadlords and Imps. Your spells restore lots of health so you ideally want to use your hero power every turn until you find Oakheart. Dragonslayer is a nice tech card to deal with Scalebanes and Operatives run in dragon priest and spiteful priest. Demonheart is great for putting a Dreadlord out of reach from damage removal or combat damage, and can also create a 6/6 Imp when it has no other target.
