Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is Normal Summoned or flipped face-up: You can banish 1 "Lightsworn" monster from your hand or GY; banish 1 card on the field. Once per turn, if your other "Lightsworn" monster's effect is activated: Send the top 3 cards of your Deck to the GY.
