Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
When this card is activated: Send 1 monster you control to the GY, or if "Golden Castle of Stromberg" is in a Field Zone, you can send 1 monster your opponent controls to the GY, instead. Once per turn, during your Standby Phase: You can target the monster that was sent to the GY by this card's effect; destroy this card, and if you do, Special Summon that monster to your field. You can only activate 1 "Iron Cage" per turn.
