Goblin Bombardment sacrifices Phyrexian Walker to deal 1 damage, and Koll, the Forgemaster returns the creature to hand because it was equipped when it died — Lightning Greaves is the glue that makes Koll's trigger fire. Phyrexian Walker costs 0 to cast, so the loop costs nothing beyond the initial setup and kills the table with uncounterable direct damage.

Repeat.

Variations

Cheaper, tighter, alternate lines

Any 0-cost creature with no color identity slots in alongside Phyrexian Walker — Ornithopter or Memnite both work if Lightning Greaves is already on board when they die. Altar of Dementia replaces Goblin Bombardment if the goal is milling instead of damage, and Purphoros, God of the Forge converts the infinite ETBs into a second kill vector without needing the sacrifice step at all.
