I have a thought.

(pauses as everybody takes cover)

I thought of era-specific tournaments - say, a 1950s tournament, only cards from 1950-1959 allowed, but you could also do f.e. an interwar tournament from 1919-1941 and countless others - that might also be capped (f.e. gold cards or below) where the top finishers are rewarded in special packs; those packs would only contain cards from the era the tournament was played in, so 1950-1959 or 1919-1941 in the prior examples.

These packs might have a slightly skewed content distribution towards higher-value cards, or maybe not; but they would of course only contain historical cards, also meaning that all perfect and diamond cards popped would be potentially extremely valuable.

I realize that there's probably a lot of work to do with the pack content generation algorithm to pull this off. but that would be one way to combat card shortages on the market, too.
