Emry, Lurker of the Loch + Displacer Kitten + Concordant Crossroads + Dark Sphere

Emry, Lurker of the Loch

Displacer Kitten

Concordant Crossroads

Dark Sphere

How it works

1. Activate Emry by tapping it, allowing you to cast Dark Sphere from your graveyard.
2. Cast Dark Sphere by paying 0.
3. Displacer Kitten triggers, blinking Emry.
4. When Emry enters, it triggers, causing you to mill four cards.
5. Activate Dark Sphere by tapping and sacrificing it.
6. Repeat.

This clever loop uses Displacer Kitten as the engine that untaps and resets your board state every time you cast a noncreature spell. By using Emry, Lurker of the Loch to continuously cast Dark Sphere right back out of your graveyard, the Kitten's blink ability triggers to cycle Emry in and out of play—freshly milling cards on each reentry while Concordant Crossroads ensures Emry can tap immediately without waiting around for summoning sickness.
