Muldrotha, the Gravetide

Displacer Kitten

Extruder

Valeria Richards, Precocious

How it works

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

This intricate loop centers around Muldrotha, the Gravetide, whose ability allows you to repeatedly play your artifacts straight from the graveyard. Extruder provides the crucial sacrifice outlet to feed this engine while pumping your creatures full of +1/+1 counters, and since Extruder is itself an artifact, it can easily become part of your recycled permanent supply. Meanwhile, Valeria Richards, Precocious makes your noncreature spells cheaper and rewards your first cast of the turn with a card, while Displacer Kitten provides the engine's heartbeat, blinking Muldrotha every time a noncreature spell is cast so you can continuously reset your permissions and keep the cycle going.
