Did they forget to make this fast? It might have been worth considering if it was. As it stands, if this card isn't in your opening hand then most of the time you are effectively paying three resources to get +2 in a skill test, the equivalent of Unexpected Courage. Comparing it to the other neutral skill cards like Perception or Overpower is even more unfavorable because those allow you to draw a card if you succeed and are completely free. There are a handful of situations where the Ace of Rods will give you +4 in a test, but even then it is still too pricey to seriously consider.
One positive is that because it gets removed after use, putting two in your deck doesn't result in a dead draw. Preston Fairmont can use it as a means of flexing on other investigators to show how little he cares for efficiency.
