Liquimetal Coating turns Jan Jansen, Chaos Crafter into an artifact so it can sacrifice itself into its own ability loop; Dross Scorpion untaps Jan Jansen each time a creature dies, resetting the engine without spending additional mana. The combo slots into Mardu artifact shells — Breya, Etherium Shaper is the obvious commander, but Jan Jansen as commander runs every piece in the command zone except Skullclamp, which any artifact tutor finds.

Cheaper, tighter, alternate lines

Liquimetal Torque replaces Liquimetal Coating as a mana-rock that does the same job and doubles as early ramp. If Skullclamp is the removal target, any sac outlet that converts draws — Phyrexian Arena won't do, but Erebos, God of the Dead or a free discard outlet paired with Underworld Breach can close — the loop produces enough death triggers and mana to find a substitute kill.
