You can Special Summon this card (from your hand) by returning 1 'U.A.' monster you control to the hand, except 'U.A. Playmaker'. You can only Special Summon 'U.A. Playmaker' once per turn this way. When another 'U.A.' monster you control declares an attack: You can have this card lose exactly 800 ATK, and if it does, your attacking monster gains 800 ATK.
