This is moreso a community thing, but I think it would be really neat if there was a Wiki for this game, to allow players to quickly view cards, learn how cards such as Paper and Frankenstein's monster work, as well being generally useful for the playerbase in general. Perhaps ingame rewards or a discord role to encourage frequent contributors of the Wiki would advance this idea.

there is. It's at https://cards-the-universe-and-everything.fandom.com/wiki/Cards,_the_Universe_and_Everything_Wiki I haven't updated all the cards for a few months so recent releases aren't there (don't add them manually, I can get them there with an API once I have more time). Playing tips / explanations for cards like Frankenstein would be great, fill free to add (you can see the format with the Fomalhaut notes).
Other things that need some effort is the combos list
