For most card players, getting the ability to search your deck for something and putting it into your hand is pretty awesome. For some CCGs, cards that do just that are more expensive just because they do that. It's a fantastic advantage to have.
But this isn't a CCG, it's Arkham Horror LCG.
On paper, Research Librarian seems perfectly suitable for any would-be Tome user:
- At 2 resources, it's a really good 1st action, 1st turn play.
- He comes with 1 health and 1 sanity, so he acts as a nice shield.
- I can't emphasize how crazy some people get over tutoring for a card.
So he should be an auto-include for someone like Daisy Walker, right? ...Eh, kinda.
Research Librarian's greatest strength is also his downfall. Should you happen to draw your tomes before him, he just becomes a very flimsy 1 health/1 sanity shield, which, for 2 resources, is not very efficient. He also takes up the ally slot, which could be better used to fit whatever you're building toward.
His only usefulness is, like I said, on action 1 of turn 1 to search for your tome. After that, feed him to Forbidden Knowledge or shield some of that Dynamite Blast you had to use. Otherwise, keep him in your hand for that agility test. He's a one off at best, at least in my opinion.
