Emry, Lurker of the Loch casts Lion's Eye Diamond from the graveyard for free; every cast triggers Displacer Kitten to blink Emry, which re-mills four cards and resets the line. Lightning Greaves is the glue — it gives Emry haste and keeps the equip cost at zero so the loop starts the turn everything lands.

Variations

Cheaper, tighter, alternate lines

Emry needs haste to go off immediately; if Lightning Greaves is answered, Swiftfoot Boots is the fallback, though the equip jumps to one mana. The loop produces infinite colored mana but no built-in kill — pair it with Thassa's Oracle or Jace, Wielder of Mysteries, both of which win on an empty library that Emry's mill fills.
