Emry, Lurker of the Loch + Mirran Spy + Tormod's Crypt

Emry, Lurker of the Loch

Mirran Spy

Tormod's Crypt

How it works

1. Activate Emry by tapping it, targeting Tormod's Crypt.
2. Cast Tormod's Crypt from your graveyard by paying 0.
3. Mirran Spy triggers, untapping Emry.
4. Activate Tormod's Crypt by sacrificing it.
5. Repeat.

This clever loop relies on Emry, Lurker of the Loch to continually pluck Tormod's Crypt right back out of your graveyard for zero mana, fueling an endless stream of artifact triggers. Because Tormod's Crypt is an artifact spell, casting it triggers Mirran Spy's static ability to untap Emry, keeping the recursion engine running indefinitely. Meanwhile, Emry's cost reduction, affinity for artifacts, makes replaying her a breeze if she ever leaves the battlefield, while Tormod's Crypt conveniently sends itself back to the graveyard when sacrificed so Emry can target it all over again.
