Muldrotha, the Gravetide grants the ability to recast Sol Ring from the graveyard each loop; Krark-Clan Grunt sacrifices it for a power boost and Displacer Kitten blinks Muldrotha to reset the artifact-spell-per-turn restriction. The loop runs on two colorless per cycle — Sol Ring produces exactly that — making it self-sustaining the moment all four pieces are on the battlefield.

Recipe

How it works

Prerequisites

You have not cast an artifact spell using Muldrotha this turn.

Steps

Activate Sol Ring by tapping it, adding .
Activate Krark-Clan Grunt by sacrificing Sol Ring.
Cast Sol Ring from your graveyard by paying .
Displacer Kitten triggers, blinking Muldrotha.
Repeat.

Result

Infinite LTB; Infinite ETB; Infinite storm count; Infinitely powerful creature until end of turn

Variations

Cheaper, tighter, alternate lines

Any other one-mana artifact that produces at least two mana fills Sol Ring's slot — Mana Crypt runs the same loop for zero, which is strictly faster. Krark-Clan Grunt is the narrow piece here; if it's removed, the storm count and ETB triggers still accumulate but the creature pump is gone, so pair it with Altar of the Brood or an Impact Tremors effect rather than relying on combat to close.
