Pendulum Effect
Once per turn: You can target 1 'D/D' monster you control; its Level becomes 4, and if it does, it gains 400 ATK and DEF. (These effects remain even if this card leaves the field.)
Monster Effect
When this card is Pendulum Summoned from your hand while you control a 'D/D' monster, except 'D/D Cerberus': You can target 1 Continuous Spell Card in your Graveyard; add it to your hand.
