This mesmerizing loop turns the graveyard into your personal workshop, anchored by Emry, Lurker of the Loch pulling Dark Sphere back into play again and again for zero mana. Every time you cast that zero-cost artifact from the graveyard, Displacer Kitten’s evasion triggers to blink Derevi, Empyrial Tactician, resetting the battlefield so Derevi's entrance untaps Emry to do it all over again. The setup even leverages Emry's built-in affinity and lets you crack Dark Sphere along the way, spinning an endless cycle of artifact sacrifices, enters-the-battlefield effects, and storm count.
