“Other cards you control cannot be destroyed by your opponent's card effects. You can only use each of the following effects of "Blue-Eyes Jet Dragon" once per turn, and can only activate them while "Blue-Eyes White Dragon" is on your field or in your GY. If a card(s) on the field is destroyed by battle or card effect: You can Special Summon this card from the GY (if it was there when the card was destroyed) or hand (even if not). At the start of the Damage Step, if this card battles: You can target 1 card your opponent controls; return it to the hand.”
