Urza, Prince of Kroog's activated ability costs 6 but produces two token copies of Grim Monolith thanks to Anointed Procession; each token taps for three colorless, funding the next activation. Lightning Greaves' zero-equip cost is the linchpin — swapping it between fresh tokens satisfies the tap requirement and keeps the loop self-sustaining. The whole package lands in artifact-token shells built around Urza himself or Shorikai, Genesis Engine, where doubling effects and free equip matter already.

Result

Infinite ETB; Infinite tapped creature tokens

Cheaper, tighter, alternate lines

Parallel Lives replaces Anointed Procession if the deck skews green, though Azorius identity locks that out here — Mondrak, Glory Dominus is the on-color alternative doubler. The loop produces infinite ETB triggers but no damage on its own; close with Reckless Fireweaver, Marionette Master, or Altar of the Brood already in play, since infinite tapped tokens don't swing for the win without a drain or mill outlet.
