Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is in your GY: You can banish 1 LIGHT and 1 DARK monster from your GY, except "Chaos Betrayer"; Special Summon this card in Defense Position, but banish it when it leaves the field. If this card is Special Summoned: You can target 1 card in your opponent's GY; banish it. You can only use each effect of "Chaos Betrayer" once per turn.
