Hearthpwn

This is the deck that I used to defeat heroic Gothik the Harvester. I was checking to see how easily his deck could be sustained through and realised that it is relatively easy to take everything to the face and just let him run out of cards.

When Gothik runs out of cards he still uses his ability every turn so takes massive fatigue damage very quickly. I did not attempt to do him damage at all throughout the game and still won fairly easily.

Intelligent use of Brawl and Doomsayer is important. They can be used to kill your own spirits if they stack up too high but Gothik also throws things out in a burst so try to save Brawl for when it will kill 4+ targets. Try not to burn through Doomsayers too early because they are useful midgame as well, he seems to prioritise smashing your face with the 5/6s rather than double hit the Doomsayers, and he will stupidly use Corruption while they are on the board.

The most dangerous cards in his deck for you are the Undertakers that grow with every deathrattle card he plays, basically a mini Questing Adventurer for him. I prioritised killing these as quickly as possible.

The Crazed Alchemists will kill any spirit that you don't feel like taking damage from, and the Sunfury Protectors and Rampages will prompt Gothik to use his removal on his own spirits to stop you from taking damage.

If I were to modify the deck for more runs I would consider taking Abomination over the Crazy Alchies. Gothik himself runs 3+ of these and they are the card in his deck that will help you the most. Use of cheap damaging abilities can start a chain reaction within these and his Unstable Ghouls, potentionally turning a Mortal Strike into a board wipe.

Good luck!
