I just tested it out and those seeds aren't as useful on the higher levels because all the great jokers have some sort of condition on them, like they only last for 5 turns. I guess those are mostly for making runs from the starting level. Not that they are useless later, they still give great jokers. You just don't want to use most of them.If a game has a randomized start that heavily influences your chances for success, I think it should provide an option to guarantee a good start.
Though I suppose Balatro does in the sense that it allows you to use a specific seed, so once you find a good start you can just keep using that, or you can use one of the many seeds shared by other players.
That's the biggest problem in the last couple of levels. Just getting anything so you can play the game for longer than a few hands.
