Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
You can only control 1 "Valkyrie Erda". While you control this card, Special Summoned by the effect of a "Valkyrie" card, all face-up monsters your opponent controls lose 1000 ATK. Any card destroyed by battle or card effect that would be sent to your opponent's GY is banished instead.
