Muldrotha, the Gravetide + Displacer Kitten + Ravenous Intruder + Helm of Awakening

Muldrotha, the Gravetide

Displacer Kitten

Ravenous Intruder

Helm of Awakening

How it works

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

This clever loop turns Muldrotha, the Gravetide into a relentless engine by leveraging Helm of Awakening to reduce an artifact's cost down to zero, letting you recast it straight from your graveyard turn after turn. Each time you cast that free artifact, Displacer Kitten triggers to blink Muldrotha, cleverly refreshing your permissions and your board state. Meanwhile, Ravenous Intruder stands ready to devour the recurring artifact for infinite sacrifice triggers, pumping itself to lethal size in the process.
