Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Equip only to a Dragon Synchro Monster you control. "Red Dragon Archfiend" equipped with this card is unaffected by your opponent's activated effects. Once per turn, during your Main Phase: You can make the ATK of all monsters your opponent currently controls become equal to the equipped monster's. Once per turn, when an attack is declared involving the equipped monster: You can target 1 monster in your opponent's GY; banish it, and if you do, the equipped monster gains ATK equal to that banished monster's, until the end of this turn.
