Cast Lion's Eye Diamond by paying 0.
Displacer Kitten triggers, blinking Emry.
When Emry enters, it triggers, causing you to mill four cards.

Repeat.
This fascinating loop revolves around the synergy between Emry, Lurker of the Loch and Lion's Eye Diamond, where Emry’s tap ability lets you repeatedly cast the Diamond right back out of your graveyard for zero mana. Whenever you cast that noncreature artifact, Displacer Kitten triggers to blink Emry, resetting its tap ability and triggering a fresh mill of four cards upon re-entry. Meanwhile, Samut, Tyrant Smasher keeps the engine moving by giving your creatures haste, ensuring Emry is immediately ready to tap again the moment it returns to the battlefield.
