Creature — Elemental
3 / 2
Flying
When this creature enters, investigate twice. (To investigate, create a Clue token. It's an artifact with "

, Sacrifice this token: Draw a card.")
Evoke


(You may cast this spell for its evoke cost. If you do, it's sacrificed when it enters.)
You can't sacrifice a Clue to activate its own ability and also to activate another ability that requires sacrificing a Clue (or any artifact) as a cost, such as that of Lonis, Cryptozoologist.
