If we're talking about the Dragon's Eye, then it works with location and gate cards. If you look at the contents of AH, you'll note 63 Location cards (so 7 per 9 neighborhoods), 67 Mythos and 49 Gate cards (those being the OW encounter deck).
Heh... Good thing someone else checked. I always use it for Arkham which is probably why I couldn't remember if it allowed you to draw different gate cards.
