Muldrotha, the Gravetide + Displacer Kitten + Krark-Clan Grunt + Samut, the Driving Force

Muldrotha, the Gravetide

Displacer Kitten

Krark-Clan Grunt

Samut, the Driving Force

How it works

1. Cast the artifact from your graveyard by paying 0.
2. Displacer Kitten triggers, blinking Muldrotha.
3. Activate Krark-Clan Grunt by sacrificing the artifact.
4. Repeat.

This loop relies on Muldrotha, the Gravetide granting you recursive access to an artifact from your graveyard, while Samut, the Driving Force provides a crucial cost reduction that makes casting that artifact free. Whenever you cast it, Displacer Kitten triggers to blink Muldrotha, resetting her permission so you can replay the artifact again after it hits the bin. To facilitate that graveyard trip, Krark-Clan Grunt acts as a convenient sacrifice outlet that also scales its own power using the artifacts you endlessly cycle.
