This clever loop spins entirely around the synergy between Emry, Lurker of the Loch and Displacer Kitten, transforming a humble zero-mana artifact into a self-sustaining engine. When you cast Tormod's Crypt from your graveyard using Emry's tap ability, the Kitten's Avoidance trigger blinks Emry, resetting her tap ability by bringing her fresh back to the battlefield. Meanwhile, Rising of the Day ensures Emry has haste so she can tap immediately without waiting, while its passive pump to legendary creatures is just a neat bonus. You can repeat this sequence endlessly—casting Tormod's Crypt for zero, sacrificing it for its effect, and blinking Emry back in—to churn through your deck and rack up infinite triggers.
