This is a very situational card. Usually, it's a testless clue that costs you a horror, an action, and a resource. Which isn't all that efficient a way to gain clues, unless you have some way to lessen the costs. However, if you have some way to make the costs less severe, it's a useful card for any investigator who doesn't have great investigating skills. The best use of it I've seen was a Yorick deck where he had ways of dealing with horror (Meat Cleaver and Cherished Keepsakes being the primary ones), and with his ability, he could put the raven into play without taking an action.
