Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Reveal any number of "Predap" cards in your hand, then target that number of face-up monsters your opponent controls; place 1 Predator Counter on each one, and if you do, any of those monsters that are Level 2 or higher become Level 1 as long as they have a Predator Counter. If your "Predaplant" monster would be destroyed by battle, you can banish this card from your GY instead.
