Auriok Steelshaper reduces Skullclamp's equip cost to zero on Crookshank Kobolds, so equipping kills the 0/1 immediately and draws two cards — Koll, the Forgemaster then returns the Kobolds to hand for free recasting. The whole loop costs nothing but storm count, which means any Boros equipment commander running Koll as a support piece can win at instant speed with two mana floating and a full grip incoming.

Steps

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

Result

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

Variations

Cheaper, tighter, alternate lines

Ornithopter or Shield Sphere can substitute for Crookshank Kobolds as any 0/1 or 0/2 creature that costs zero and dies to Skullclamp; Crookshank Kobolds is simply the cleanest zero-mana option. Once the library is drawn, close with Aetherflux Reservoir off the storm count or Grapeshot if the deck splashes for it — the draw engine itself doesn't kill.
