Hearthpwn

Basically cubelock with + 2x Meat Wagon ,2x Summoning Portal, 2x Phantom Militia .

-cut x2 doomsayer, x2 hellfire, 1x faceless manipulator. 

new concept:

Instead of doomsayer hellfire or faceless, you have the option to combat aggro with meatwagon as a threat in addition to lackey that your opponent doesnt want to trade with. Meat wagon summons, summoning portal which statically makes your minions cost 2 less while in field. Hence making milita cost 1 instead of 3.

think of this situation:

your at 19 life vs a aggro paladin vs a full board and a vulnerable minion with 4 attack.  (turn 5 opponent

Your turn(turn 5 for you, you have coin).

You suicide meatwagon(your opponent went face, (its a 1/4/your playing cubelock they know that)). for portal. Then with your 5 mana you play up to 6(coin) phantom militias. 12/24 taunt stats spread apart 6 minions with a protected portal waiting to discount your lackey better.

Basically a controllable spreading plague in warlock.
