Muldrotha, the Gravetide + Displacer Kitten + Ugin, the Ineffable + Arcbound Ravager

Muldrotha, the Gravetide

Displacer Kitten

Ugin, the Ineffable

Arcbound Ravager

How it works

1. Cast the artifact from your graveyard by paying 0.
2. Displacer Kitten triggers, blinking Muldrotha.
3. Activate Arcbound Ravager by sacrificing the artifact.
4. Repeat.

This clever loop lets you sacrifice and replay an artifact indefinitely by leveraging Muldrotha, the Gravetide's ability to cast permanent spells from your graveyard. Each time you replay that artifact for free, Displacer Kitten's trigger blinks Muldrotha to completely refresh your permissions for the turn, allowing you to cast it again. Meanwhile, Arcbound Ravager provides the mandatory sacrifice outlet to send the artifact back to the graveyard while growing larger with its +1/+1 counters. Ugin, the Ineffable quietly helps enable the loop by discounting the costs of your colorless spells, ensuring you can keep churning through your graveyard without running out of mana.
