Hearthpwn

This is a control warlock build which revolves around getting thicc walls from Master Oakheart and also Bloodreaver Gul'dan, then turning them into massive swing turns with Void Ripper to leverage the massive health of your minions into burst attack damage.

Based around a combo I've wanted to do for a while now involving Dirty Rat + Void Ripper + Shadowflame (on dirty rat) . If this is pulled off at the right time while your taunt minions are on the board in decent quantity, not only do you clear their board and erase one of the minions they were holding in their hand, but you now have a board of high-attack minions ready to punch the enemy's face. Because of Void Ripper 's effect, the 6-attack Shadowflame proc on Dirty Rat will most likely kill everything on it's own, as enemy minions will usually have more health than attack, or both stats will be at 6 or less anyway.

Rin makes an appearance as a backup measure against control/grinder decks that look to push you towards fatigue or if the void ripper combos  simply don't come together due to bad draws.

Update 1: Added N'zoth as well as a Scaled Nightmare. N'Zoth creates another chance at a huge swing turn with void ripped and in general just makes it that much harder to beat in the late game. Scaled nightmare is a tough minion with 2 attack which can psuedo-heal with void ripper, as it can be flipped when its attack gets high to restore health. Skull of the Man-ari helps dig the deck out of trouble if it draws void lords

Update 2: -1 Carnivorous Cube +1 Vulgar Homunculus . 2 cubes is just too greedy with N'zoth in the deck now, and was causing the early game to run too slow. Added a Vulgar homunculus for an early taunt, which synergizes well with spellstones, skull, oakheart, guldan etc.
