Hearthpwn

The spookiest deck on ladder. This deck is so spooky that all your opponents will concede. Easy legend

Edit: With the release of KOFT, (most of) the inferior zombie filler has been replaced with glorious spooky skeltals. Doot Doot 

Reasons for each card

Undertaker/ Boneguard: Early Game spookiness

Devilsaur: Is spooky skeletal and dinosaur 11/10

Mortal Coil: Skulls are spooky

Power Overwhelming: Makes skeltals more spooky, but kill them (sadly)

Siphon Soul Calcium :  Steals enemies calcium and gives it to us.

Spookmage Thalnos: Combos with Siphon Calcium so you can steal more calcium

Drain Calcium: Weaker than Siphon Calcium, but also gets the spook damage from spookmage thalnos

Rivendare: Rides a skeltal horse and as a bonus doubles our spookrattles

Kelthuzad: 8/10 Spook and keeps rest of army alive to keep spooking

Spookmaw: The spookiest of the dragons 7/10

Black Knight: Very Spook

Skeltal Knight: The master of spook himself. Often skeltal knight will win games single handly by his sheer spookiness. He is a god amongst skeletons and all spooky skeletons want to be like him. Everytime he wins a joust, you get calcium and strong bones. Doot Doot

 Lich King: The king of skeletons himself

 

The reason Rattling Rascal is not included is because his cuteness is stronger than his spookiness, which lowers this deck's win rate
