Pretty much what they said about Whitton Greene (0), but more so. Who likes this? Ursula, Daisy, and Luke, maybe Harvey, assuming he's running tomes. Joe or Rex could use the boost, but, unless they are running tomes and/or relics, not so great. On the other hand, I am probably going to try and cram Dream Diary into every deck I can, Whitton is a damn sight better than (although more expensive than) Research Librarian. Warning. You probably want to pack Pathfinder and/or Shortcut to make sure you trigger her ability.
