Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Pay half your LP; destroy 1 "Dinomorphia" monster you control and 1 card your opponent controls. When your opponent activates a card or effect, while your LP are 2000 or less: You can banish this card from your GY; you take no effect damage from your opponent's card effects this turn. You can only activate 1 "Dinomorphia Brute" per turn.
