This clever loop spins entirely around the graveyard synergy of Emry, Lurker of the Loch, who taps to pull Jeweled Lotus right back out of your graveyard for repeated free castings. Every time you cast that artifact, Displacer Kitten's blink ability triggers to exile and instantly return Emry to the battlefield, resetting her tap ability and triggering a fresh mill of four cards along the way. Sacrificing Jeweled Lotus for mana to fund the engine—or perhaps just utilizing its cheap casting cost alongside Emry's artifact-reduction affinity—sustains the loop while Dragonlord Kolaghan stands ready in the command zone to take advantage of the resulting infinite mana and storm count.
