For its XP cost, i can consider this a very good card...but not great. And the only reason I downgraded it to very good is because it has no icons. For a 4xp card, i think it should have had two icons in there. I base this on several playthroughs with Rex where in the mid-late game, i am usually swimming with cards.
Fast. Play only during your turn.
Choose an investigator at your location. That investigator draws 3 cards.
If you are wondering how strong this card is, just imagine that it says for no resources and no actions, an investigator at your location draws 10% of their deck. Yeah, I'd say that is pretty good.
Currently, only 6 investigators can take this (every Seeker except Norman). Among them, the hardest thing about taking Cryptic Research is choosing to prioritize this. 4XP is a lot of XP to spend on a card and Seekers have a lot of places they could be spending their XP. Add to that the fact that Seekers have a lot of card draw even with no XP at all. It's truly not hard to draw through your entire deck with Seeker, even with no XP at all. If you are worried about redundancy, then think of it this way: Cryptic Research could help you consolidate some card drawing power into one card, leaving you more space to add other effects.
However, don't neglect the multiplayer possibilities. There are other factions that have a hell of a time drawing cards, Guardians in particular. If you are doing a classic Seeker + Guardian multiplayer campaign, this can help your Guardian draw through their deck to get cards they need, while you draw through your own deck with your own tools.
This is a really powerful card. Compared to Preposterous Sketches,its 4xp more. So you can easily consider these two cards are upgraded version to another. For 4xps you get: Fast Two cost lower No need to be in a place with clues Can be another one
How can you complain this card? For 4xps, it’s a fair trade.
Especially in Minh Thi Phan,you can effectively draw more icons to help others.
