Emry, Lurker of the Loch + Displacer Kitten + Delif's Cone + Derevi, Empyrial Tactician

Emry, Lurker of the Loch

Displacer Kitten

Delif's Cone

Derevi, Empyrial Tactician

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 Derevi.
4. When Derevi enters, it triggers, untapping Emry.
5. Activate Delif's Cone by tapping and sacrificing it.
6. Repeat.

This clever engine transforms the humble Delif's Cone into an infinite loop by leveraging Emry, Lurker of the Loch to recast the zero-mana artifact from your graveyard over and over again. Every time you cast that artifact, Displacer Kitten steps in to blink Derevi, Empyrial Tactician, whose fresh entry triggers an untap of Emry so the whole cycle can begin anew. Because the artifact is sacrificed to its own ability along the way, this loop cleanly bypasses restrictions and yields an endless procession of enters-the-battlefield, leaves-the-battlefield, and sacrifice triggers.
