Zirda, the Dawnwaker reduces Myr Propagator's activation cost from 3 to 1; Lightning Greaves equips for free and gives haste, letting the freshly tapped Propagator token immediately be sacrificed to Krark-Clan Ironworks for 2 colorless — a net gain each loop. Red-white artifact commanders like Osgir, the Reconstructor or Akiri, Line-Slinger have the tutor density to find all four pieces, and the death trigger flood fuels anything watching the board.

Cheaper, tighter, alternate lines

Swiftfoot Boots can replace Lightning Greaves if hexproof is more valuable than shroud in the local meta, though the equip cost rises to 1. The loop needs a sink for the colorless mana — Walking Ballista or Altar of Dementia closes out the game once the engine runs, and both sit cleanly in red-white artifact strategies.
