Yeah, I also don't really see a solution on how they could turn things around. What they should start with imo is to set a maximum cards of 1 player that can exist based on the rarity. If the maximum is reached, an older card of that player needs to be burned to mint a new one. At least that would create some scarcity and an initial burn mechanic. Limited cards now feel like free common cards and Rare has turned into the new Limited. It's always the same with these games, printer goes brrr en economy colapses making it that a lot of players leave and nobody new is coming in.
