Muldrotha, the Gravetide + Displacer Kitten + Megatog + Valeria Richards, Precocious

Muldrotha, the Gravetide

Displacer Kitten

Megatog

Valeria Richards, Precocious

How it works

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

This clever loop turns your graveyard into a perpetual engine by leveraging Muldrotha, the Gravetide's ability to repeatedly cast a permanent card from the graveyard on your turn. Whenever you cast that artifact, Valeria Richards, Precocious helps grease the wheels by reducing its casting cost while replacing itself with a card draw on your first noncreature spell, while Displacer Kitten triggers off that same noncreature cast to blink Muldrotha, resetting your permissions. Finally, Megatog stands ready to sacrifice the artifact to grow infinitely large and clear the way with trample, allowing you to replay the sacrificed artifact right back out of the graveyard and do it all over again.
