Very interesting card that will definitely find use somewhere. At the time of release this is only the second card that lets you investigate with (the other being a telescanner upgraded Hyperphysical Shotcaster ) and unlike the shotcaster, it's level 0.
Crowbar does only grab one clue, so it's not Scene of the Crime; but it's another way that the fighter can help get clues when there aren't enemies on the field, and if you're completely solo, one clue is usually enough anyway.
I think Mark Harrigan probably benefits the most, getting +3 skill for the test compared to using Although he may want a Bandolier later in the campaign so he can still wield a 2-handed weapon.
