This card is very similar to Working a Hunch - they both do the same thing for the same cost with a few differences:
- Working a Hunch is fast.
- Art Student has 2 horror soak and 1 damage soak.
- Art Student takes up an ally slot.
So, Art Student effectively costs one more action than Working a Hunch, provides some soak, but takes up a slot that could be prohibitive to playing other useful cards. In-class, I don't know if Seeker investigators will take either, since I think they'd rather put their resources towards playing assets that will let them gain clues over and over again rather than getting a one-time clue. Sure, Working a Hunch will help you get one clue from a high-shroud location... but how are you going to get the rest of them?
I think most Seeker investigators are not going to be interested in Art Student as an Ally option. Dr. Milan Christopher is generally the preferred choice for clue gathering as a flat +1 with resource generation is overall a more useful set of effects than gaining a single clue.
However, I think Art Student is a good ally for Roland Banks. Roland's is lower than most main-class Seeker investigators, so he likes having the testless clue option to crack high-shroud locations. He also has low sanity, so the 2 points of horror soak are welcome, especially in an ally that can be discarded without too much consequence. Roland's other main ally, Beat Cop, definitely adds a valuable +1, but it's twice the cost of Art Student and Roland is usually spread pretty thin on resources.
I think there's a good way to build a Roland Banks deck without Beat Cop, and I think in those builds Art Student is one of his better choices. There is some minor synergy with Calling in Favors and Laboratory Assistant where you can use the allies for their "entering play" effect, have them soak one horror, then return them to your hand so that you can use their "enter play" effect again. Roland Banks likes these smaller, cheaper Seeker allies for horror soak.
So, while Art Student isn't necessarily the best card, it definitely has its uses. In decks that count on the occasional testless clue and want cheap Seeker allies for horror soak, I think it's a reasonable choice.
