Muldrotha, the Gravetide

Displacer Kitten

Atog

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 Atog by sacrificing the artifact.
4. Repeat.

This fascinating engine comes together through an intricate dance of graveyard recursion and trigger mechanics, where Muldrotha, the Gravetide allows you to repeatedly cast an artifact straight from your graveyard while its presence is continuously refreshed by blinking it away and back. Every time you deploy that artifact, Displacer Kitten triggers off the noncreature spell to exile and return Muldrotha to the battlefield, resetting its once-per-turn casting permissions. Meanwhile, Atog stands ready to devour the recurring artifact for a growing power boost, while Samut, the Driving Force serves as the ultimate enabler by reducing the cost of your noncreature spells through its speed mechanic, potentially making the recast free to keep the loop going indefinitely.
