Activate Emry by tapping it, allowing you to cast Delif's Cone from your graveyard.
Cast Delif's Cone by paying 0.
Displacer Kitten triggers, blinking Emry.
When Emry enters, it triggers, causing you to mill four cards.
Activate Delif's Cone by tapping and sacrificing it.
Repeat.
This clever loop relies on Emry, Lurker of the Loch pulling Delif's Cone straight from your graveyard every time she enters the battlefield. Whenever you recast that zero-mana artifact, Displacer Kitten triggers to blink Emry, resetting her tap ability and churning through your library with endless self-mill. Meanwhile, Akroma's Memorial quietly stands guard, granting your entire team haste so Emry can tap immediately without waiting around for summoning sickness.
