Hearthpwn

Update: Added some more strong battlecry to benefit Shudderwock & removed one Hecklebot to remove anti-synergy with Shudderwock in late game.

This deck was spawned from the question 'how can i ruin everyone's day?' and this was the result.

This deck has 4 cards which effectively silence.
It has 3 cards which can clear the board (4 if you count Hagatha the Witch)
It has 2 anti weapon cards.
It has 2 Unseen Saboteurs to kill spell based combos.
It has a Hecklebots to kill minion based combos and fatigue your opponent.
It has Archivist Elysiana to extend fatigue.
It has Shudderwock which will a) fatigue your opponent and/or b) replace your deck again and/or c) clear the board
It has loads healing cards to keep you going deep into the game.

It is super fun to play, and the win rate i've had it with it is pretty good, and even if you lose, its a super fun game!

It's a bit expensive (sorry!)
