Flotsam // Jetsam (MKM-247) - Murders at Karlov Manor Foil

Mill three cards. Investigate. (Create a colorless Clue artifact token with ", Sacrifice this artifact: Draw a card.")

Each opponent mills three cards, then you may cast a spell from each opponent's graveyard without paying its mana cost. If a spell cast this way would be put into a graveyard, exile it instead.
