Emry, Lurker of the Loch + Displacer Kitten + Tormod's Crypt + Fires of Yavimaya

Emry, Lurker of the Loch

Displacer Kitten

Tormod's Crypt

Fires of Yavimaya

How it works

1. Activate Emry by tapping it, allowing you to cast Tormod's Crypt from your graveyard.
2. Cast Tormod's Crypt by paying 0.
3. Displacer Kitten triggers, blinking Emry.
4. When Emry enters, it triggers, causing you to mill four cards.
5. Activate Tormod's Crypt by tapping and sacrificing it.
6. Repeat.

This loop turns Tormod's Crypt into a self-sustaining engine by leveraging Emry, Lurker of the Loch's tap ability to repeatedly pull the zero-mana artifact right back out of your graveyard. Every time you recast it, Displacer Kitten's trigger blinks Emry to untap her and instantly refresh her ability while fueling your self-mill with four new cards on re-entry. Meanwhile, Fires of Yavimaya grants the necessary haste to ensure Emry can tap immediately upon entering the battlefield, binding the whole mechanical dance together into an infinite loop.
