Lurrus of the Dream-Den + Displacer Kitten + Lithatog

Lurrus of the Dream-Den

Displacer Kitten

Lithatog

How it works

1. Cast the artifact from your graveyard by paying 0.
2. Displacer Kitten triggers, blinking Lurrus.
3. Activate Lithatog by sacrificing the artifact cast in step 1, giving it +1/+1 until end of turn.
4. Repeat.

This loop relies on casting a zero-mana artifact from your graveyard using Lurrus of the Dream-Den's permission, which fuels the engine by letting you replay that same permanent turn after turn. Every time you cast that noncreature spell, Displacer Kitten's avoidance ability triggers to blink Lurrus, resetting any state-based tracking and keeping the recursion flowing. Meanwhile, Lithatog sits ready to devour the recurring artifact for fuel, turning those repeated cycles into an infinitely large threat until end of turn.
