Let's keep it simple: Any XP you spend on that fancy Exceptional item is essentially wasted if you don't draw that card during the scenario. Even hard mulligans can fail and leave you scrambling to get set up. This card is one of the best ways to make sure you pull The Skeleton Key or The Red Clock, and even if you are lucky during mulligan, you're likely running other items that it's still helpful to draw into early.
I pretty much always take this card before buying my expensive Item assets unless I'm playing a character who has access to repeatable card draw or better (or more specific) tutors like Mr. "Rook", Research Librarian, or Prepared for the Worst + Stick to the Plan.
