Skullclamp equipped to Kobolds of Kher Keep costs 0 to attach, kills the 0/1 immediately, and draws 2; Koll, the Forgemaster returns the Kobold to hand for free because it's an equipped creature. Auriok Steelshaper reduces the equip cost to 0, which is what makes the loop clean — without it, the equip costs 1 each iteration and the engine stalls. The combo lives in Koll commander builds and any Boros artifact or equipment shell that already wants Skullclamp.

Steps

Equip Skullclamp to Kobolds of Kher Keep for .
Kobolds of Kher Keep dies.
Skullclamp triggers, drawing you 2 cards.
Koll triggers, returning Kobolds of Kher Keep to your hand.
Cast Kobolds of Kher Keep.
Repeat.

Result

Infinite card draw; Near-infinite death triggers; Near-infinite ETB; Near-infinite LTB; Near-infinite storm count

Variations

Cheaper, tighter, alternate lines

The loop runs the same with any other 0-mana creature in place of Kobolds of Kher Keep — Ornithopter or any free artifact creature works as the sacrifice target. Without Auriok Steelshaper, the equip cost is 1 per loop, which is not infinite and drops the engine to a strong-but-fair card advantage package. Pair the infinite draw with Aetherflux Reservoir, Reckless Fireweaver, or Impact Tremors to convert the storm count and ETBs into a kill.
