Verzauberung
Wenn die Flüchtigen Erinnerungen ins Spiel kommen, stelle Nachforschungen an. (Bringe einen farblosen Hinweis-Artefaktspielstein mit „

, opfere dieses Artefakt: Ziehe eine Karte" ins Spiel.)
Immer wenn du einen Hinweis opferst, legt ein Spieler deiner Wahl die obersten drei Karten seiner Bibliothek auf seinen Friedhof.
If you sacrifice a Clue to pay the cost of a spell or ability, Fleeting Memories's second ability will resolve before that spell or ability.
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.
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.
