Hearthpwn

The point of this deck is to stay alive and draw cards until you finish your opponents off with a 24 dmg combo to the face! It sounds gimmicky but it's more consistent than you might think. This deck has a major advantage in midrange matchups, does great against control and is still viable against aggro decks.

10 mana wombo combo for 24 dmg =
Arcane Golem + 2x Power Overwhelming + Faceless Manipulator

9 mana combo for 16 dmg =
Arcane Golem + Power Overwhelming + Faceless Manipulator

Total amount of healing = 28 (not counting fear of Molten Giants)

What to Mulligan for?

Druid        -    Fel Cannon, Hellfire (both great against Shade of Naxxramas)
    
Hunter        -    Kezan Mystic, Fel Cannon, Darkbomb, Mortal Coil

Mage        -    Kezan Mystic, Hellfire, Darkbomb, Earthen Ring Farseer

Paladin        -    Mind Control Tech, Hellfire, Mortal Coil

Priest        -    Earthen Ring Farseer, Darkbomb

Rogue        -    Darkbomb, Annoy-o-Tron, Earthen Ring Farseer

Shaman        -    Fel Cannon, Mind Control Tech, Hellfire, Darkbomb

Warlock        -    Big Game Hunter, Ironbeak Owl (+ Mortal Coil)

Warrior        -    Ironbeak Owl (for Armorsmiths)

A few tips

- Unless you are facing aggro decks you want to tap as much as possible!

- It's fine to use parts of your combo against aggro

- Use Recombobulator on Antique Healbot (there are many 5 mana taunts)

- Keep the Owl for Tirion if you are facing mage

For me there is no other deck that is as fun as this one while still being competitively viable. I'd love to hear your opinions on it!
