The 5 combo pieces

What must be in place

You control at least two additional artifacts for each time you've cast The Cyber-Controller from the command zone this game.
NOTE: This combo may fail if the opponents do not mill any creature cards. Having additional artifacts on the battlefield and/or mana available help mitigate this.

How to execute it

  1. Activate Urza's first ability three times by tapping three artifacts you control, adding {3}.
  2. Cast The Cyber-Controller from the command zone, choosing for X to equal the amount of artifacts you control minus twice the number of times The Cyber-Controller has been cast from the command zone this game, but paying a total of {3} due to Mycosynth Lattice and Mycosynth Golem.
  3. When The Cyber-Controller enters the battlefield, it triggers, causing each opponent to mill X cards, and then putting all creature cards milled this way onto the battlefield face down under your control as 2/2 Cyberman artifact creatures.
  4. Activate Urza's first ability by tapping The Cyber-Controller, adding {1}.
  5. Activate Krark-Clan Ironworks by sacrificing The Cyber-Controller, adding {C}{C}.
  6. Choose to return The Cyber-Controller to the command zone from your graveyard.
  7. Repeat from step 2 as able, or until each opponent has milled their library.
