How it works

  1. Cast Retraction Helix by paying U mana, targeting a creature you control that doesn't have summoning sickness.
  2. Cast Sewer-veillance Cam by paying U mana.
  3. When Sewer-veillance Cam enters, it triggers, untapping a creature you control.
  4. Activate Urza's first ability by tapping Sewer-veillance Cam, adding U mana.
  5. Activate the creature targeted by Retraction Helix by tapping it, returning Sewer-veillance Cam from the battlefield to your hand.
  6. When Sewer-veillance Cam leaves the battlefield, it triggers, untapping the creature tapped in step 5.
  7. Repeat from step 2.
