Muldrotha, the Gravetide + Displacer Kitten + Sarcatog + Bilbo, Thief in the Night

Muldrotha, the Gravetide

Displacer Kitten

Sarcatog

Bilbo, Thief in the Night

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 clever engine is anchored by Bilbo, Thief in the Night, whose static ability reduces the cost of spells cast from your graveyard by {1}, letting you deploy a free zero-mana artifact repeatedly. Each time you cast that noncreature spell, Displacer Kitten triggers to blink Muldrotha, the Gravetide, refreshing your permissions and battlefield state while you simultaneously sacrifice the artifact to fuel Sarcatog's growing power. Because Muldrotha allows you to play a permanent type from your graveyard each turn and Bilbo lets you cast an artifact from your graveyard, the pieces lock together seamlessly into an infinite loop of entry, departure, and sacrifice triggers.
