Muldrotha, the Gravetide + Displacer Kitten + Umbral Collar Zealot + Helm of Awakening

Muldrotha, the Gravetide

Displacer Kitten

Umbral Collar Zealot

Helm of Awakening

How it works

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

This ingenious engine turns your graveyard into an endless workshop by leveraging Muldrotha, the Gravetide to repeatedly cast an artifact for free. With Helm of Awakening reducing the artifact's mana cost down to zero, every single cast triggers Displacer Kitten to blink Muldrotha, cleverly resetting your per-turn casting restrictions so you can play the exact same artifact right back out of the graveyard. To keep the loop going, Umbral Collar Zealot acts as the sacrificial outlet, feeding the artifact to its ability to bin it back into the graveyard while generating an infinite stream of triggers and surveil depth.
