Activate Emry by tapping it, allowing you to cast Dark Sphere from your graveyard.
Cast Dark Sphere by paying 0.
Displacer Kitten triggers, blinking Emry.
When Emry enters, it triggers, causing you to mill four cards.
Activate Dark Sphere by tapping and sacrificing it.
Repeat.
This clever loop relies on Emry, Lurker of the Loch pulling Dark Sphere straight from your graveyard into play for free. Every time you cast that artifact, Displacer Kitten triggers to blink Emry, resetting her tap ability while feeding your self-mill engine with fresh cards from your library. Meanwhile, The Fire Crystal reduces your red costs and grants your creatures haste, ensuring everything flows seamlessly together while you churn through your deck.
