Emry, Lurker of the Loch + Displacer Kitten + Fervor + Lion's Eye Diamond

Emry, Lurker of the Loch

Displacer Kitten

Fervor

Lion's Eye Diamond

How it works

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

This clever loop uses Displacer Kitten as the engine that untaps and resets your board every time a noncreature spell is cast. Emry, Lurker of the Loch lets you repeatedly pull Lion's Eye Diamond right back out of your graveyard, fueling each iteration with the three mana it provides upon sacrifice. Meanwhile, Fervor ensures Emry isn't hindered by summoning sickness, granting the haste needed to tap and restart the cycle immediately upon re-entering the battlefield.
