Emry, Lurker of the Loch + Chakram Retriever + Lion's Eye Diamond

Emry, Lurker of the Loch

Chakram Retriever

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. Chakram Retriever triggers, untapping Emry.
4. Activate Lion's Eye Diamond by sacrificing it.
5. Repeat.

This clever loop centers on Emry, Lurker of the Loch utilizing her tap ability to continually pull Lion's Eye Diamond from the graveyard, allowing you to sacrifice the Diamond in response to its own mana generation to fuel further castings. Meanwhile, Chakram Retriever sits quietly on the board, its static triggered ability watching for you to cast a spell during your turn and dutifully untapping Emry each time Lion's Eye Diamond is replayed. Because the Diamond costs nothing to cast and yields three mana upon sacrifice, the Retriever's untaps create a self-sustaining engine that floods your mana pool while generating an infinite storm count and endless artifact triggers.
