This card is absolutely wild. It's incredibly efficient for the price, with the most easily searchable keyword in the game (Research Librarian, Whitton Greene), gives a +2 boost at level 0 on an item which is unconditional, and further boosts the most important resource in the game; card draw, all the while giving 4 uses for 3 money for a single hand slot. Fingerprint Kit exhausts and has 3 uses while only giving a +1 boost and costs 4 resources. Further, the uses are secrets, which, while this isn't a strong contender to boost the uses, the fact is you can very easily with Astounding Revelation or Eldritch Sophist, or Truth From Fiction. Did you need more handslots to hold it and get more boosts with Magnifying Glass? Arcane Enlightenment is right there
In Daisy this feels like a no brainer because she has the extra action just to use this. Harvey loves this because its an easy and reliable way to proc an activation of drawing a card during his turn. Minh can use it to keep powering her Skill commitment engine. Ursula can also trigger it using her extra action. This feels good for Trish, and Joe, and Roland as well. Hell, if you're clueving with Jenny, Charlie or Lola it seems like a no brainer. Darrell may want this over test-at-0, just for card draw. Mandy likes it, Norman, Rex looooooves the +2 boost. Everyone who can take it should consider it. The fact it doesn't exhaust can make for incredibly powerful turns with Amanda if she has a Deduction under her, if you set up a turn to just investigate with this 3 times going bam bam bam. She needs a little bit more of a boost than the others perhaps, but its crazy how efficient this is compared to any other asset at level 0 that has the Investigate keyword on it. Even Luke who has a higher brain stat, could respec to using this for the first few scenarios going standard seeker with Dr. Milan and Magnifying Glass and this for test at 7 until he gets more XP to dump Sixth Sense (4) or your spell of choice. He can even be running Perception and Deduction with this and be perfectly fine until he gets some 10-20XP.
I could compare this with Cryptographic Cipher, but that at least has a potential of gaining you 3 free investigates. But dammit I will compare, because this gives you 4 investigates you were going to do anyway, with a +2 (where the Cipher had a -2 to shroud on the action) and you can draw an extra card most of the time. It costs the same amount of resources, and has 1 extra use. The power creep is real. The closest comparison in fighters is Glory. Guardians or any fighter have very few benefits at level 0 the way this just gives it to you. The upgraded Thompson turning bullets into money, or On The Hunt getting you money for killing, or the upgrades on Runic Axe. Outside of Investigator powers like Tony's Bounties or Zoey's engagement, there simply is no comparison with how well Seeker cluevers get rewarded compared to Guardian fighters.
Once again, Seekers simply receive cards that straight up reward them for doing what they do best in the most efficient way. Even if there were an upgrade for this, I have no idea what it would need to add to make this better, because I could see this being in a deck from campaign start to campaign finish. I would run this over Magnifying Glass simply because I get the boost, and if I'm drawing more cards, I get to my skills such as Deduction or any of my other good cards much faster that it's irrelevant.
The Scarlet Keys had so many good cards for every class, and many archetypes, but this is subtly one of the best and I could very well see it as a new staple.
