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 control matchups while it's 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
    
Hunter        -    Acidic Swamp Ooze, Fel Cannon, Darkbomb

Mage        -    Hellfire, Darkbomb, Mind Control Tech

Paladin        -    Mind Control Tech, Acidic Swamp Ooze, Hellfire, Mortal Coil

Priest        -    Earthen Ring Farseer

Rogue        -    Acidic Swamp Ooze

Shaman        -    Mind Control Tech, Hellfire, Darkbomb

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

Warrior        -    Acidic Swamp Ooze, Ironbeak Owl

A few tips for playing against...

Druid        -    use Fel Cannon / Hellfire to get rid of Shadow of Naxxramas
    
Hunter        -    it's fine to use parts of the combo, don't tap too much!

Mage        -    if it's Mech Mage it's fine to use parts of the combo

Paladin        -    safe an Owl for Tirion and Faceless him if you can!

Warlock        -    if it's Handlock don't attack face at all until you get combo lethal

Warrior        -    use Owls on Armorsmiths

General tips

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

- Hellfires are great to set up for lethal without them expecting shenanigans

- Think twice before you use your Owls - taunts can ruin your day

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

- If you have Alexstrasza I'd consider putting her in for a MC Tech
