Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Equip only to a monster you control. If the equipped monster battles an opponent's monster, the equipped monster's original ATK/DEF is doubled during damage calculation only. If you control a monster other than the equipped monster, send this card to the GY. You can only control 1 "Solitary Sword of Poison".
