Emry, Lurker of the Loch + Displacer Kitten + Derevi, Empyrial Tactician + Lion's Eye Diamond

Emry, Lurker of the Loch

Displacer Kitten

Derevi, Empyrial Tactician

Lion's Eye Diamond

How it works

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

This ingenious loop leverages Emry, Lurker of the Loch to repeatedly pull Lion's Eye Diamond out of your graveyard, utilizing the diamond's mana-generating sacrifice ability to fuel its own cast. Each time you cast that artifact, Displacer Kitten's avoidance trigger blinks Derevi, Empyrial Tactician. The resulting entrance of Derevi then untaps Emry, resetting your activator so the entire sequence can loop indefinitely for infinite colored mana, storm count, and triggers.
