Odd-Eyes Persona Dragon X DARK Level 5 [ Dragon / PendulumEffect ] ATK 1200 DEF 2400 P Scale 1 Once per turn, during the End Phase, if your opponent activated a card or effect this turn that targeted 1 "Odd-Eyes" Pendulum Monster you controlled (and no other cards) while this card was in your Pendulum Zone: Special Summon this card, 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"
