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 casting and sacrificing Delif's Cone repeatedly from your graveyard using Emry, Lurker of the Loch's tap ability, which allows you to churn through your deck while generating infinite artifact triggers. Every time you cast the zero-mana artifact, Displacer Kitten's trigger blinks Emry back onto the battlefield to untap her and mill more cards, sustaining the chain indefinitely. Meanwhile, Anger rests quietly in your graveyard, granting haste to ensure your creatures are always ready to act if needed, provided you control a Mountain.
