Muldrotha, the Gravetide

Displacer Kitten

Grinding Station

Shuri, Wakandan Inventor

How it works

1. Cast the artifact from your graveyard by paying 0.
2. Displacer Kitten triggers, blinking Muldrotha.
3. When the artifact enters, Grinding Station triggers, untapping Grinding Station.
4. Activate Grinding Station by tapping it and sacrificing the artifact.
5. Repeat.

By leveraging Muldrotha, the Gravetide to repeatedly cast a zero-cost artifact directly from your graveyard, you set off a cascading chain of permanent triggers that mills your opponents out of the game. Every time that artifact hits the stack, Displacer Kitten blinks Muldrotha to keep your permissions fresh, while Shuri, Wakandan Inventor ensures your artifact spells stay as cheap as possible to facilitate the loop. Meanwhile, Grinding Station converts every single iteration of the artifact entering and leaving the battlefield into an infinite supply of untapped activations, letting you sacrifice and mill away your targets indefinitely.
