How it works

  1. Activate Metalworker by tapping it and revealing at least three artifact cards from your hand, adding at least six C.
  2. Activate Urza by paying 6, creating a token copy of Seat of the Synod that is a 1/1 Soldier.
  3. When the Seat of the Synod token enters the battlefield, Retreat to Coralhelm triggers, untapping Metalworker.
  4. Repeat.
  5. If you have four or more artifact cards in hand, this combo nets infinite colorless mana, and you may target any artifact you control to get infinite copies of them.

This engine is powered by Metalworker, which taps to generate an avalanche of colorless mana based on the artifacts hiding in your hand. Urza, Prince of Kroog then uses that bounty to fuel his activation, creating a token copy of Seat of the Synod that hits the battlefield as a 1/1 artifact creature. Because that token counts as a land entering the battlefield, Retreat to Coralhelm triggers to untap Metalworker, allowing you to feed the loop all over again.
