Skynet

High Level Machine/Psychic deck for Domain Format, a casual multiplayer free-for-all format inspired by MTG Commander format.

Using Psychic Processor as the Deck Master gives me access to DARK, Machine, Psychic or Cyberse monsters.

The main goal of this deck is to spam Psychic Processor to summon all the monsters you can from your hand, attack directly and then go for a Xyz Summon if needed. Each time you use your Deck Master, you're going to add it back to your hand by his own effect in the next Standby Phase, so you don't to worry about the Deck Master tax.

How do you put Ruinforce in the GY? 
Machina Gearframe + Machina Unclaspare, Machina Air Raider, Machina Irradiator, Machina Fortress, Machina Redeployment, Revolving Switchyard and Graceful Charity.

Synergies:

• Cyber Dragon + DNA Surgery/Clockwork Night: Go for Chimeratech Fortress Dragon using the board. Pair with Heavy Storm for maximum efficiency.
• Number XX: Utopic Dark Infinity + any BIG special summoned monster: Maybe this is the best way to gain LP in the deck. Your best targets are Machina Ruinforce, Number 77: The Seven Sins, Number 81: Superdreadnought Rail Cannon Super Dora and Superdreadnought Rail Cannon Juggernaut Liebe.
• Number 97: Draglubion + Number 92: Heart-eartH Dragon and Number C92: Heart-eartH Chaos Dragon
  • Number 92: Heart-eartH Dragon: Summon this one if you need to pressure the table with his banish effect or the reflect damage. 
  • Number C92: Heart-eartH Chaos Dragon: Summon this one if you need to gain LP or need a board negate.

Notable techs:

• Revolving Switchyard: A search for our High Level Machines and enable Rank 10 plays.
• Psychic Arsenal: Pay 600 LP to add any of your DARK Machines? Yes please!
• Original Bamboo Sword: Remember! You can attack directly with your DM's special summoned monsters during that turn, add this for a surprise Raigeki.
• Limiter Removal: Old but GOLD! 

Cards for further testing:

• More High Level Machines like Ancient Gear Reactor Dragon, Snow Plow Hustle Rustle, Carnot the Eternal Machine, etc.
• C-3PO and R2-D2.
• Maybe more Gizmeks.
• Decanelogue - Valdrath, Number 95: Galaxy-Eyes Dark Matter Dragon and Number 9: Dyson Sphere.

We play on the Domain Format discord often. Anyone can come ask questions or learn the format to build a deck.
