Muldrotha, the Gravetide + Displacer Kitten + Sarcatog + Cloud Key

Muldrotha, the Gravetide

Displacer Kitten

Sarcatog

Cloud Key

How it works

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

This loop turns your graveyard into an infinite resource engine, fueled by the staggering flexibility of Muldrotha, the Gravetide allowing you to replay permanents from your graveyard turn after turn. By lowering costs with Cloud Key (naming artifact), you can cast a zero-mana artifact repeatedly from the graveyard. Each time you do, Displacer Kitten triggers to blink Muldrotha, resetting your permissions and blinking key permanents. Finally, Sarcatog acts as the necessary sacrifice outlet to bin the artifact and keep the loop churning infinitely, while also growing massively in power from all the sacrifices.
