Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target 1 card your opponent controls and 1 card in their GY; send that card on the field to the GY, and if you do, Set the other card from the GY to your opponent's field. You can only activate 1 "Terrors of the Overroot" per turn.
