Extra Deck Pendulum Monsters

Extra Deck Pendulum Monsters are a Xyz, Fusion, and/or Synchro monsters that are also Pendulum monsters, meaning while they are stored in the Extra Deck face-down, they can be activated directly to the Pendulum Zone. They are also subject to most Pendulum Monster rulings, which means they also return to the Extra Deck face-up if they would be sent from the field to the Graveyard. Also, if they have a Level (Xyz Monsters don't have Levels for instance), they can also be Pendulum Summoned provided they are face-up in the Extra Deck. (They can still be Xyz, Fusion, or Synchro Summoned normally.)
