[START OF COMBO]This combo can be formed with The Cyber-Controller, Urza, Lord High Artificer, Krark-Clan Ironworks, Mycosynth Golem, Mycosynth Lattice

Color identity: UB
Mana cost: 
Steps:
  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.[END OF COMBO STEPS]

  - Near-infinite mill[END OF COMBO RESULT][END OF COMBO]
