Emry, Lurker of the Loch + Displacer Kitten + Tormod's Crypt + Sparring Mummy

Emry, Lurker of the Loch

Displacer Kitten

Tormod's Crypt

Sparring Mummy

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. Displacer Kitten triggers, blinking Sparring Mummy.
4. When Sparring Mummy enters, it triggers, untapping Emry.
5. Activate Tormod's Crypt by tapping and sacrificing it.
6. Repeat.

This delightful loop turns the mechanical synergy of Emry, Lurker of the Loch and Displacer Kitten into a perpetual motion machine fueled by graveyard recursion. Because casting Tormod's Crypt from your graveyard for zero mana counts as casting a noncreature spell, Displacer Kitten triggers to blink Sparring Mummy, whose entry ability immediately untaps Emry, Lurker of the Loch to do it all over again. Meanwhile, sacrificing Tormod's Crypt to its own ability fits seamlessly into the loop, allowing Emry, Lurker of the Loch to continuously target and recast the exact same artifact while generating an endless storm count and continuous entry and exit triggers.
