Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target up to 5 cards in your opponent's GY and the same number of your opponent's banished cards; banish those targets from their GY, and if you do, return those banished targets to the GY. You can only activate 1 "Terrors of the Underroot" per turn.
