Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target 1 "Red-Eyes" monster you control; equip this card to it. It can make up to 2 attacks on monsters during each Battle Phase. You can send this Equip Card to the GY, then target 1 Effect Monster on the field; equip that target to the monster this card was equipped to, and if you do, while a monster is equipped to it by this effect, its ATK/DEF become equal to the original ATK/DEF of that equipped monster.
