Lightning Greaves

• WOTC Official Reminder Textofficial rules
  Equip — Equip [cost] ([cost]: Attach to target creature you control. Equip only as a sorcery.)

• WWizards of the Coast2020-08-07
  Official Ruling
  You can't simply unequip Equipment from a creature. If Lightning Greaves is attached to the only creature you control, you won't be able to attach other equipment to it (or target it with anything else) until you have another creature to which you can attach Lightning Greaves.
• WWizards of the Coast2020-08-07
  Official Ruling
  If a creature enters the battlefield under your control and gains haste, but then loses it before attacking, it won't be able to attack that turn. This means that you can't use one Lightning Greaves to allow two new creatures to attack in the same turn.

  Kederekt Leviathan + any permanent based creature clone (Phyrexian Metamorph, Clone, Vesuvan Doppelganger, Dance of Many) has great synergy. Here's why. Cast Kederekt to bounce everything. Next turn, attack whoever has nothing in play. Then cast the clone on Kederekt, bouncing everything again. Rinse & repeat. Add in Volrath's Stronghold for even more fun. If they happen to kill one of your two bouncers, you just draw it next turn and replay it. If you add in Lightning Greaves (and have the mana to replay it every turn because you'll keep bouncing it), you can swing against zero defenses, because they won't even be able to use Maze of Ith.
