The owner of target creature or enchantment puts it into their library second from the top or on the bottom. You create a Clue token. (It's an artifact with "{2}, Sacrifice this token: Draw a card.")

- 2 October 2025Clue tokens are artifact tokens with "{2}, Sacrifice this token: Draw a card."
- 2 October 2025Creating a Clue token this way isn't the same thing as investigating. Notably, an ability that triggers whenever you investigate won't trigger because of creating a Clue token this way.
- 2 October 2025The permanent's owner chooses whether to put it second from the top or on the bottom of their library. If multiple cards are put into the library this way (such as when this spell targets a melded permanent), that permanent's owner puts all the cards second from the top or all the cards on the bottom. They put them in whatever order they wish and do not need to reveal the order.
