حجرة الثياب ر.م.

(This card is always treated as a "F.A." card.)
Target 1 "U.A." or "F.A." monster you control or in your GY; add it to the hand, and if you do, you gain 500 LP, then you can apply this effect.
● Reveal any number of "U.A." and/or "F.A." monsters in your hand, shuffle them into the Deck, then draw cards equal to the number of shuffled cards.
You can only activate 1 "U.A. Locker Room" per turn.
