Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
4 Level 5 monsters When an opponent's monster declares an attack: You can destroy all cards your opponent controls. If this card has "Number 69: Heraldry Crest" as material, it gains this effect. ● Once per turn: You can detach 1 material from this card, then target 1 face-up Xyz Monster your opponent controls; this card gains ATK equal to that face-up monster's original ATK, also, this card's name becomes that monster's, and it gains that monster's original effect. These effects last until the End Phase. * The above text is unofficial and describes the card's functionality in the OCG.
