Emry, Lurker of the Loch + Displacer Kitten + Village Bell-Ringer + Tormod's Crypt

Emry, Lurker of the Loch

Displacer Kitten

Village Bell-Ringer

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. Displacer Kitten triggers, blinking Village Bell-Ringer.
4. When Village Bell-Ringer enters, it triggers, untapping all creatures you control.
5. Activate Tormod's Crypt by tapping and sacrificing it.
6. Repeat.

This clever loop turns Emry, Lurker of the Loch into a recursive engine by utilizing her tap ability to repeatedly pull Tormod's Crypt out of the graveyard and cast it for zero mana. Because the zero-cost artifact is a noncreature spell, its casting triggers Displacer Kitten to blink Village Bell-Ringer, which in turn wipes away Emry's tap status by untapping all your creatures upon re-entry. Tormod's Crypt acts as the perpetual noncreature catalyst that keeps the Kitten blinking and the Bell-Ringer untapping everything in sync, letting you repeat the cycle endlessly to flood the board with triggers.
