Demonmail Hauberk sacrifices Cathodion to equip Koll; Cathodion's death trigger adds three colorless mana, and Koll's trigger returns itself to hand. Lightning Greaves at zero equip cost lets Cathodion be sacrificed immediately on recast without waiting for priority. The whole loop runs at sorcery speed but produces infinite ETB, LTB, and sacrifice triggers off a commander most tables won't see coming.

Cheaper, tighter, alternate lines

Any free-sacrifice outlet that triggers Koll can substitute for Demonmail Hauberk if the Hauberk gets destroyed — Ashnod's Altar won't loop cleanly here since Koll's return needs the equipment on him, so keep the Hauberk protected. Walking Ballista or Reckless Fireweaver turns the infinite storm count and ETBs into a kill; without a damage sink the loop is spectacular and does nothing.
