Once per turn, during the End Phase, if your opponent activated a card or effect that targeted exactly 1 “Odd-Eyes” Pendulum Monster this turn while you controlled that monster: Special Summon this card from your Pendulum Zone, and if you do, place 1 face-up “Odd-Eyes” Pendulum Monster from your Extra Deck in your Pendulum Zone, except “Odd-Eyes Persona Dragon”.
Once per turn, during either player’s turn: You can target 1 face-up monster on the field that was Special Summoned from the Extra Deck; negate that face-up monster’s effects until the end of this turn.
