Muldrotha, the Gravetide lets Sol Ring be recast from the graveyard each loop; feeding it to Lithatog resets the artifact slot and triggers Displacer Kitten, which blinks Muldrotha to reset the slot again. The engine lives in a UBRG shell that already wants Muldrotha as its commander, so the three supporting pieces are the only dedicated ask.

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 Lithatog's first ability by sacrificing Sol Ring, giving Lithatog +1/+1 until end of turn.
Cast Sol Ring from your graveyard by paying .
Displacer Kitten triggers, blinking Muldrotha.
Repeat.

Result

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

Variations

Cheaper, tighter, alternate lines

Any zero- or one-mana artifact can replace Sol Ring as the sacrifice fodder — Tormod's Crypt or Mishra's Bauble both pay for themselves with leftover mana and keep the loop clean. Lithatog is the narrowest piece; if the gameplan is storm count or ETB abuse rather than a combat kill, redirect to Impact Tremors or Altar of Dementia as the closer since Lithatog's buff doesn't survive the turn.
