Koll, the Forgemaster returns Kobolds of Kher Keep to hand whenever it dies equipped, and Lightning Greaves costs zero to re-equip each loop, so the whole cycle costs nothing after setup. Goblin Bombardment is the kill condition and the engine simultaneously — every sacrifice deals 1 damage and triggers Koll, which reloads the next iteration. Red-white aristocrats shells running Koll as commander assemble this with any artifact tutor or creature tutor fetching Kobolds.

Steps

Equip Kobolds of Kher Keep with Lightning Greaves.
Sacrifice Kobolds of Kher Keep to Goblin Bombardment to deal 1 damage to any target.
Koll triggers, returning Kobolds of Kher Keep to you hand.
Cast Kobolds of Kher Keep.
Repeat.

Result

Infinite damage; Infinite death triggers; Infinite ETB; Infinite LTB; Infinite sacrifice triggers; Infinite storm count

Variations

Cheaper, tighter, alternate lines

Any free creature works in place of Kobolds of Kher Keep — Ornithopter and Phyrexian Walker both cost zero and preserve the loop. Shrapnel Blast and similar one-shot spells don't replace Goblin Bombardment here; the sacrifice outlet must be repeatable and free, so Ashnod's Altar is a colorless alternative that swaps damage for infinite colorless mana instead.
