Hearthpwn

I really wanted to build a deck around Void Contract, and this is a decent one I ended up with.
It plays like a mid range Druid Spiteful Summoner, as DOOM! can be used like an Ultimate Infestation. To both refill and clean the board.
Against aggro, the deck relies on the usual mana cheated synergies with Skull of the Man'ari and Voidcaller.
I have never seen Enslaved Fel Lord played before, and it's quite effective as board clearer, especially with Animated Broomstick.
Explosive Sheep, Mistress of Mixtures and Mind Control Tech help a lot here too.
Against combo deck the fun disruption begins with Gnomeferatu and later with Void Contract. The later which is totally unexpected by the opponent.
To avoid too much havoc from the contract, the deck has Envoy Rustwix, Kanrethad Ebonlocke and Archivist Elysiana.
Bloodreaver Gul'dan and N'Zoth, the Corruptor can be enough for late game, even with an empty deck.
Expired Merchant is a valuable tool to duplicate a strong end card. It can be played directly with Animated Broomstick to avoid silence and other such effects.
Spiteful Summoner with Animated Broomstick is very good too.

I was surprised by the number of decks combo or not, which are heavily disrupted by a first Void Contract.

Very fun deck, not a only a meme, as it can win several games.
