For me this is an auto include in Luke Robinson simply because you can use it to investigate the Dream-Gate. The Pointless Reality side doesn't care that you acquire a clue, only that you succeed the investigation. Map the Area would attach to the Dream-Gate but at the end of your turn you would discard Map the Area when Dream-Gate was set aside.
I personally enjoy using De Vermis Mysteriis alongside this card for that reason: Get stuck in the Pointless Reality, use Map the Area to avoid 2 horror, then on a following turn use De Vermis Mysteriis to play it again on a fixed location where it could remain an attachment for the remainder of the scenario rather than getting removed from the game.
With this card you have the option of Luke's signature weakness going from take 3 Draw/Resource/Play actions and take 2 horror to spend 1 action and 1 card and pass a skill test.
