I believe something like this is necessary to keep the game fresh, but since we have 3 more months of FFG-supported tournaments, it’s probably too early to discuss it now. Discussions should focus more on who the most qualified people to steer the game into the future would be, and to create a centralised committee to elect them, cause right now there’s a group on facebook discussing the game’s future, a group on Slack discussing the gmae’s future, and there’s probably a couple of different Discord servers doing it as well somewhere.
I think a group like that is most likely to get the community behind the if it’s led by people who are well-recognised and respected by everyone in the community. So anybody who is , for example, a former World Champion, or a prolific deckbuilder with 1 billion NRDB published decks, or a well-known podcast host, or whatever else you feel makes you likely to get people’s support, you should step up, get other people like you together, and go into all those different forums and social media channels and try to get people behind you. That doesn’t mean that the job of rotating packs in and out, making custom cycles, publishing new MWLs, or whatever else will necessarily fall to you - you could just be the committee that assigns people to do those jobs. If you’re well-respected by the community, we just need your face.
