Demonmail Hauberk sacrifices Myr Moonvessel to equip Koll, the Forgemaster; Koll's trigger returns the Myr to hand, and Myr Moonvessel's death trigger adds one colorless to recast it. Lightning Greaves is the glue — equipping the Myr for zero before each sacrifice keeps Koll's trigger active by confirming the Myr was an equipped creature. The table sees a commander-centric loop that asks only for four permanents and one generic mana to start moving.

Cheaper, tighter, alternate lines

Skullclamp replaces Demonmail Hauberk as a sacrifice outlet if drawing the library matters more than equip triggers — attach to Myr Moonvessel, sacrifice to Skullclamp's triggered ability, draw two. The loop produces infinite storm count and death triggers but no direct damage; pair it with Altar of Dementia for mill, Impact Tremors for drain, or Reckless Fireweaver as the kill condition.
