① If destroyed by battle and sent to the GY:
You can Special Summon 1 Fairy with 1500 or less ATK from your Deck,
or, if "Sanctuary in the Sky" is on the field, you can Special Summon 1 "Airknight Parshath", instead.
● This effect activates in the Damage Step, so it can never be negated by "Royal Oppression".
Cards like "Bottomless Trap Hole" and "Torrential Tribute" can never be used in response to this Summon.
