WARNING: this deck is bad even for a bad deck
The combo is play stoneshaker and have a soulfire drake die for a 4 cost charge west wind herald. You discard decimate by some mean and charge west wind herald to face, decimating for a total of 12 damage. Next turn, haunting scream or play a second herald for another 12 damage and hope you dealt 1 damage during the rest of the game. gg ez
