Myr Propagator's activated ability costs 3 and a tap to make two token copies of itself; Lightning Greaves re-equips for 0 to untap the original, and Ashnod's Altar sacrifices the tapped original plus one token for 4 colorless — netting 1 mana per loop while a token army accumulates. Primal Vigor doubles each token creation, so every activation yields four copies instead of two, making the Altar sacrifice redundant to the loop's growth. Green artifact-combo shells running Urza, Lord High Artificer or Emry, Lurker of the Loch find this line attractive because every piece does independent work.

Doubling Season replaces Primal Vigor and does the same doubling job without giving opponents the benefit, though it costs more mana to resolve. Skullclamp or Goblin Bombardment converts the infinite death and ETB triggers into a kill if the token flood alone isn't finishing the table; the engine generates the resources, the closer is on the pilot to supply.
