Cerulean Sacred Phoenix of Nephthys — Ruling

Effetto 1

The effect of this card that destroys "Nephthys" cards in your hand and/or on your field and monsters on your opponent's field is an Ignition Effect. (It does not target.)
Destroying "Nephthys" cards in your hand and/or on your field, and destroying monsters on your opponent's field do not happen simultaneously.

The effect that Special Summons this card from the Graveyard during your Standby Phase is a Trigger Effect that activates in the Graveyard. (It does not target.)
This effect does not start a Chain when this card is destroyed by a card effect and sent to the Graveyard. The effect activates and starts a Chain during your next Standby Phase after that. (If this card was not previously Ritual Summoned, such as if it was sent to the Graveyard from your hand or Deck, you cannot activate its effect that Special Summons it from the Graveyard.)
