Emry, Lurker of the Loch casts Lotus Petal from the graveyard for free; that cast triggers Displacer Kitten, which blinks Emry, which re-mills and resets the loop. Lightning Greaves provides the haste that lets Emry tap immediately on the turn it enters — without it, the loop stalls until Emry survives a full turn cycle.

Variations

Cheaper, tighter, alternate lines

Swiftfoot Boots can replace Lightning Greaves in pinch, though the hexproof over shroud is irrelevant mid-combo and the equip costs one. The loop produces colored mana but no built-in kill — finish with Thassa's Oracle off the repeated mill triggers or cast a lethal Stroke of Genius once the mana is infinite; every piece here is an artifact, so Whir of Invention finds the missing one.
