When Scrutiny of the Guildpact enters the battlefield, you may choose a creature card in your hand. If you do, that card perpetually
incorporates (Incorporate perpetually adds an additional casting cost to that card, adding any new colors from that cost, and adds abilities/text to that card for the rest of the game.) and gains "When you cast this spell, create a 2/2 white and blue Detective creature token."
Multicolored creatures you control get +1/+1.
