Creature — Human Wizard
When this creature enters, investigate. (Create a Clue token. It's an artifact with ", Sacrifice this token: Draw a card.")
"Angels and inquisitors terrorize villages, but no one seems to notice the stirring out at sea."

Rulings
Clue is an artifact type. Even though it appears on some cards with other permanent types, it's never a creature type, a land type, or anything but an artifact type.

You can't sacrifice a Clue to pay multiple costs. For example, you can't sacrifice a Clue token to activate its own ability and also to activate Alquist Proft, Master Sleuth's ability.

If an effect refers to a Clue, it means any Clue artifact, not just a Clue artifact token. For example, you can sacrifice Wrench to pay for Alquist Proft, Master Sleuth's activated ability.
