This clever loop turns Emry, Lurker of the Loch into a recursive engine by leveraging its tap ability to continually pull Dark Sphere from the graveyard for free. Because Dark Sphere is a zero-mana artifact, casting it triggers Displacer Kitten's blink ability, resetting Emry so you can mill more cards and immediately recast the Sphere. Meanwhile, Hammer of Purphoros quietly ensures your battlefield stays active and grants haste if you branch out into actual combat, though the true brilliance here is how Dark Sphere constantly enters and leaves the battlefield to fuel infinite artifact triggers and self-mill.
