Lurrus of the Dream-Den + Displacer Kitten + Extruder

Lurrus of the Dream-Den

Displacer Kitten

Extruder

How it works

1. Cast the artifact from your graveyard by paying 0.
2. Displacer Kitten triggers, blinking Lurrus.
3. Activate Extruder by sacrificing the artifact cast in step 1, putting a +1/+1 counter on a creature you control.
4. Repeat.

This loop turns Lurrus of the Dream-Den into a graveyard engine by utilizing its permission to cast a low-mana permanent once per turn—though here, we bypass that restriction entirely through clever resetting. Whenever you cast an artifact from your graveyard for zero mana, Displacer Kitten's avoidance ability triggers to blink Lurrus, clearing its restriction and allowing you to cast that same artifact again immediately. Meanwhile, Extruder sits on the battlefield waiting to sacrifice that recurrent artifact, fueling the loop while distributing an endless supply of +1/+1 counters to your creatures.
