Koll, the Forgemaster is the engine: when an equipped creature dies, Koll returns it to hand rather than the graveyard. Demonmail Hauberk provides a free sacrifice outlet that re-equips itself, Impulsive Pilferer generates the Treasure to recast itself, and Lightning Greaves's 0-equip cost lets the loop restart without paying an equip tax each cycle. Every iteration produces a death trigger, an ETB trigger, and a storm count tick — lethal with any damage-per-death or cast payoff already on the battlefield.

Cheaper, tighter, alternate lines

Swiftfoot Boots cannot substitute for Lightning Greaves here — the 1-equip cost breaks the mana neutrality of the loop. Any creature that creates a mana-positive token on death and costs 1 red can replace Impulsive Pilferer if a tighter list needs the slot. Close with Impact Tremors or Altar of the Brood, both of which trigger on the infinite casts and ETBs without needing additional setup.
