Urza, Prince of Kroog copies Thran Dynamo for 6 mana; Mondrak, Glory Dominus doubles the token output so each activation produces two copies instead of one. Lightning Greaves' 0-cost equip lets a freshly created token tap immediately for 3 colorless, funding the next Urza activation — Mondrak is the piece that makes the mana math work by doubling the return.

Variations

Cheaper, tighter, alternate lines

The loop needs a win condition layered on top — Purphoros, God of the Forge is off-color, so lean on Altar of the Brood to mill out the table or Impact Tremors if the shell splashes red; in strict Azorius, Corpse Knight is the cleanest kill attached to the infinite ETB chain. Without Mondrak, the loop collapses — protect it or tutor it first with Enlightened Tutor or Vampiric Tutor before assembling the rest.
