Skullclamp kills Crimson Kobolds the moment it's equipped, since the Kobold is a 0/1 that immediately hits -1/-0 and dies; the Clamp draws two cards while Koll, the Forgemaster returns the Kobold to hand to recast for free. Auriok Steelshaper reduces the equip cost to 0, which is what makes the loop free — without him, Skullclamp's 1 equip cost bleeds mana and the chain stops. The Boros aristocrats shell that runs Koll as commander is the natural home, since the pieces pull double duty outside the combo.

Variations

Cheaper, tighter, alternate lines

Crookshank Kobolds and Kobolds of Kher Keep are functional identical replacements for Crimson Kobolds — all three are 0/1 red creatures that cost 0. The loop draws the library but doesn't kill on its own; pair it with Aetherflux Reservoir to convert storm count into a win, or Altar of Dementia to mill opponents out once the hand and graveyard are full.
