Pumpking COTH

Genesys Deck I brought to Stuttgart Regional Genesys Tournament and got first place.

Game plan is to set up a summon of Spell Canceller (or another monster of your choice) in your opponents turn via Call of the Haunted. Support that with controlling the board with your funny pumpkin cards and generic Zombie cards.

The way to Spell Canceller is fairly easy. Pumpking combo (accessable via Pumpking himself, Ektoplasmic Fortification or Stare) gets you to Undying Legion, up to two Call of the Haunted, Call of the Forgotten and a Zombie mill (Eldlich, Mad Mauler or Mezuki for Spell Canceller combo). Next you need to mill another Zombie to the GY. Use Samurai Skull, Gozuki, Uni-Zombie or Delta. Eldich GY effect to send Delta/ Call of the Haunted and summon himself. Tribute him for Fallen Angel. Next you either use Mezuki to revive Eldich from the GY or use Mad Mauler reducing Fallen Angels level by two aummon it and synchro summon Zombie Dragon Lord after wich you use Fallen Angel effect to summon Eldich/ Mad King. Overlay for Mercurium and attach Spell Canceller.

If you don't open Pumpking, you can use your Zombie mill for Glow-Up Bloom which in turn will get you Pumpking but will lock in in Zombies (and out Mercurium).

Side Deck:

Lava Golem to break boards. You can then bounce it back with Xyz Pumpking. 

Jinzo is an alternative to Spell Canceller if you go of against a trap heavy deck.

Spiritmaster is an out against D-Fissure/ Macro Cosmos if you send it via Uni-Zombie etc...

Small going second Shaddoll Engin to send Dragon and Eldich from deck.
