Q: My opponent activates the effect of "Goddess Verdande's Guidance", declaring Monster. If the top card of my Deck is a Ritual Monster, what happens?
A: If your opponent declared Monster, and the top card of your Deck is a Ritual Monster, it cannot be Special Summoned, so the effect of "Goddess Verdande's Guidance" that adds the card to the opponent's hand is applied.[3][4]
