When a Pendulum Monster (even if it is face-down) would be sent from the field to the Graveyard, either as a Monster Card or Spell Card, it is placed face-up in the Extra Deck Zone instead. (Pendulum Monsters can cause the total size of the Extra Deck to be larger than would be allowed during Deck building.) If a Pendulum Monster is sent from the hand, Main Deck, or Extra Deck to the Graveyard; has its activation as a Spell Card or Summon negated; or is detached, it is sent to the Graveyard like normal (as it was not on the field at the time).
