Emry, Lurker of the Loch + Displacer Kitten + Delif's Cone + Mass Hysteria

Emry, Lurker of the Loch

Displacer Kitten

Delif's Cone

Mass Hysteria

How it works

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

This clever loop relies on Mass Hysteria to grant Emry, Lurker of the Loch haste, allowing her to tap immediately to cast Delif's Cone straight from your graveyard. Because Delif's Cone is a noncreature spell, casting it triggers Displacer Kitten's ability to blink Emry, resetting her tap ability and triggering her mill effect upon re-entry. You can then sacrifice Delif's Cone to its own ability, send it back to the graveyard to be recast by Emry, and repeat the cycle to churn through your entire library while generating boundless artifact and creature triggers.
