Doubling Season turns Myr Propagator's activated ability into a two-token factory; Lightning Greaves equips for free to give Propagator haste, letting it tap immediately after entering. Each cycle spends 3 and nets 4 from Ashnod's Altar — sacrificing the tapped original and one token — leaving the loop with a fresh untapped Propagator wearing the Greaves ready to repeat.

Parallel Lives substitutes for Doubling Season at lower cost if doubling effects are scarce — it hits only tokens but that's all this loop needs. The infinite colorless mana wants a sink: Walking Ballista closes the game cleanly, and Reckless Fireweaver or Purphoros, God of the Forge converts the infinite ETBs into damage if the shell is running extra colors.
