This clever loop transforms a humble piece of junk like Delif's Cone into an engine of endless iteration by weaponizing Emry, Lurker of the Loch and Displacer Kitten. Whenever you cast the Cone for zero mana from your graveyard using Emry's tap ability, Displacer Kitten's avoidance trigger blinks Emry right back onto the battlefield to untap and reset. Each fresh entry from Emry mills four more cards, while your sacrificed artifacts and creature movements feed endless triggers—all while Frostcliff Siege potentially hands your team trample, haste, a power boost, and card draw depending on your chosen mode.
