Once you've announced that you're casting a spell, players can't take actions until you've finished doing so. Notably, opponents can't try to remove cards from your graveyard to stop you from collecting evidence.

While resolving Polygraph Orb's last ability, your opponent chooses a card to be discarded without revealing it, chooses a creature to be sacrificed, or chooses to do neither. Then that player discards that card, sacrifices that creature, or loses 3 life. Your opponent can always choose to lose 3 life, even if they have cards to discard or creatures to sacrifice.
