Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If a card(s) is sent to the GY, except "In Papa's Footsteps": Banish up to 5 cards from your GY, face-down, then if 7 or more of your cards are currently banished face-down, your opponent banishes as many cards as possible from their GY (max. 5) face-down.
