Emry, Lurker of the Loch + Mirran Spy + Lion's Eye Diamond

Emry, Lurker of the Loch

Mirran Spy

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

This ingenious loop leverages Emry, Lurker of the Loch to repeatedly recur Lion's Eye Diamond from your graveyard, turning its massive mana-generating sacrifice into a renewable engine. The crucial linchpin here is Mirran Spy, whose static ability ensures that every time you cast that artifact spell from the graveyard, it untaps Emry so the process can immediately begin anew. Because Lion's Eye Diamond can be cast for free and taps into its own mana source, you are left with infinite colored mana, endless artifact triggers, and a staggering storm count ready to overwhelm your opponents.
