Pendulum Effect: Once per turn: You can pay 500 LP, then target 1 "D/D" monster you control; it gains 500 ATK (even if this card leaves the field). Unless you have a "D/D" card in your other Pendulum Zone, this card's Pendulum Scale becomes 5.
Monster Effect: When this card is Normal Summoned: You can Special Summon 1 face-up DARK Pendulum Monster from your Extra Deck, but it has its effects negated, also you cannot Special Summon monsters for the rest of this turn, except "D/D" monsters.
