Emry, Lurker of the Loch + Displacer Kitten + Delif's Cone + Deceiver Exarch

Emry, Lurker of the Loch

Displacer Kitten

Delif's Cone

Deceiver Exarch

How it works

1. Activate Emry by tapping it, targeting Delif's Cone.
2. Cast Delif's Cone from your graveyard by paying 0.
3. Displacer Kitten triggers, blinking Deceiver Exarch.
4. When Deceiver Exarch enters, it triggers, untapping Emry.
5. Activate Delif's Cone by tapping and sacrificing it.
6. Repeat.

This loop turns the modest, unassuming Delif's Cone into a relentless engine by leveraging the recursive power of Emry, Lurker of the Loch to cast it repeatedly from your graveyard for zero mana. Every time you cast that artifact, Displacer Kitten's blink ability triggers to exile and return Deceiver Exarch to the battlefield, which in turn triggers its entry ability to untap Emry so the whole cycle can begin anew. While the Cone itself gets sacrificed along the way to fuel the loop, its presence as a cheap, recasting-friendly artifact is the exact key that lets Emry feed the Kitten and Exarch indefinitely.
