Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
1 Tuner + 1+ non-Tuner monsters (This card is always treated as a "The Agent" card.) Once per turn: You can banish 1 monster from your GY, then target 1 Effect Monster on the field; change it to face-down Defense Position. This is a Quick Effect if "The Sanctuary in the Sky" is on the field or in either GY. You can banish this card from your GY; add 1 "The Sanctuary in the Sky" from your Deck or GY to your hand. You can only use this effect of "The Executor of the Underworld - Pluto" once per turn.
