Emry, Lurker of the Loch + Displacer Kitten + Coercive Recruiter + Dark Sphere

Emry, Lurker of the Loch

Displacer Kitten

Coercive Recruiter

Dark Sphere

How it works

1. Activate Emry by tapping it, targeting Dark Sphere.
2. Cast Dark Sphere from your graveyard by paying 0.
3. Displacer Kitten triggers, blinking Coercive Recruiter.
4. When Coercive Recruiter enters, it triggers, untapping Emry.
5. Activate Dark Sphere by tapping and sacrificing it.
6. Repeat.

This clever loop relies on Emry, Lurker of the Loch to continually pull Dark Sphere out of your graveyard and cast it for zero mana. Every time you cast that artifact, Displacer Kitten triggers to blink Coercive Recruiter. The freshly returned pirate then triggers its own ability to untap Emry, Lurker of the Loch so you can tap her again, while Dark Sphere sits ready in your graveyard to be recast and sacrificed once more.
