Generate a YGOPro Lua script for the following Yu-Gi-Oh card effect:
If this card is Normal or Special Summoned: You can look at the top 3 cards of your opponent's Deck, and if you do, place them on top of their Deck in any order. (Quick Effect): You can Tribute this card, then target 1 "SPYRAL" monster you control; it gains 500 ATK for each card your opponent controls. You can banish this card and 1 "SPYRAL" card from your GY, then target 1 "SPYRAL Super Agent" in your GY; add it to your hand.
