This cunning loop revolves around turning Emry, Lurker of the Loch into a self-contained recursion engine by repeatedly pulling Lotus Petal from your graveyard. Every time you recast the Petal, Displacer Kitten triggers its avoidance ability to blink Emry, wiping away summoning sickness—a delay instantly bypassed because Tannuk, Steadfast Second grants all your other creatures haste. As Emry enters and re-enters the battlefield, it mills four cards with each iteration to fuel your graveyard while generating infinite mana, storm count, and artifact triggers.
