The Dark Creator ft. Neo-Spacians

This deck aims to fill the graveyard with dark monsters for The Dark Creator, a boss whose effect can banish and summon dark monsters from your graveyard.

The Strategy

The opening play is to send Cross Porter from the deck to the graveyard with Armageddon Knight, Dark Grepher and Foolish Burial, which activates Cross Porter's effect to search for a Neo-Spacian. The Neo-Spacian you searched for could be used as fodder for cards like Convert Contact, Plaguespreader Zombie, or Brionac, Dragon of the Ice Barrier. If everything goes as planned, then you will overwhelm the opponent with resources by the time The Dark Creator is summoned.

Other Bosses

Dark Armed Dragon can easily clear boards with targeted destruction.

Dark Nephthys has a mandatory effect that destroys a spell or trap whenever she's special summoned. The Dark Creator and Call of the Haunted can trigger her effect.

Darklord Zerato's discard effect destroys all monsters your opponent controls, which helps push for game.

Some Tips

Reinforcement of the Army can search for Neo-Spacian Aqua Dolphin. It's pretty handy if you start with Convert Contact.

Junk Synchron + Cross Porter + a level 4 monster can make Mist Wurm.

The Phantom of Chaos is a great top deck that can copy The Dark Creator's effect.
