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

Emry, Lurker of the Loch

Displacer Kitten

Lightning Greaves

Lion's Eye Diamond

How it works

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

This intricate loop centers around Emry, Lurker of the Loch, who uses her tap ability to continually replay Lion's Eye Diamond from your graveyard while being repeatedly protected and refreshed by Displacer Kitten. Each time you cast the zero-mana Lion's Eye Diamond, Displacer Kitten's avoidance ability triggers to blink Emry, resetting her tap ability and triggering her mill four cards entry effect anew. Lightning Greaves plays a crucial supporting role here by granting shroud to keep Emry safe from targeted interaction while allowing her to be targeted by your own blink effects, and its zero-cost equip ensures the setup moves seamlessly. By sacrificing Lion's Eye Diamond for mana in response to the loop, you generate infinite colored mana and storm count while cycling through your entire library.
