You can also do this directly with metrics on human games. It’s something that I know wizards of the coast does with Magic the Gathering decklists, just counts the copies of cards and keeps track of the “conversion rate” of them (how likely is this deck to pass some threshold, like have a positive win percentage, given that it has this card). They are doing it primarily to spot ban targets (the paper aspect of cards means you can buff without printing a new set of cards), but it is the same idea.
