I renamed all the Walking Dead cards in deck_card to the Universes Within name but we need to support a "real" name being changed and transferred into the "flavor_name" property in future. Tricky.

We probably need to retroactively edit legal_cards.txt for a bunch of seasons?

While we are in there we could remove Precursor Golem - Sketch and the other - Sketch cards that slipped through in (I think) MOM.

If everything works correctly, our internal code should natively support both names everywhere (including the legal cards list), so editing history isn't mandatory.

#11670 handles reading rotation files. I feel like we're starting to get towards the edge-cases now.

#11700 covers league signup
