Tôi kích hoạt hiệu ứng đầu tiên của Dark Requiem Xyz Dragon , chọn mục tiêu vào một Starving Venom Fusion Dragon trên sân đối thủ của tôi. Nếu Book of Moon bị chain vào hiệu ứng này, và Dark Requiem Xyz Dragon được thay đổi thành Tư thế Phòng thủ hướng xuống, thì hiệu ứng của nó sẽ thực thi như thế nào?

2 DARK monsters on the field, except Tokens If this card is Fusion Summoned: You can make this card gain ATK equal to 1 opponent's Special Summoned monster, until the end of this turn. Once per turn: You can target 1 Level 5 or higher monster your opponent controls; until the End Phase, this card's name becomes that monster's original name, and replace this effect with that monster's original effects. If this Fusion Summoned card is destroyed: You can destroy all your opponent's Special Summoned monsters.
