Prof's video on a points system I think gets closer to it, but I don't think rating a deck off of the points of the cards in the deck is as useful as treating the brackets/points more like a step pyramid of bans. Which would allow for unbans to happen, or rather, place them on a lower tier of ban.

The difference between Golos and Iona is pretty big, I don't think Iona should be flat unbanned, but if cards are on a 0-7 point scale, Iona at 5 and Golos at 7 means events/pods can run at 'things 4 and under are legal.' or 'you can run a single 7 in your deck.'
