Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
Target an equal number of "Fire King" monsters you control and cards your opponent controls; destroy them. If a "Fire King" card(s) you control would be destroyed by card effect, you can banish this card from your GY instead. You can only use 1 "Fire King Sky Burn" effect per turn, and only once that turn.
