Blogatog: While we continue to do Universes Beyond, the Magic in-universe sets also serve an important function. Having sets that don’t have to interface with outside partners has a lot of advantages.
IMO I think we ultimately see 3 UB sets per year, 3 “in universe” i.e. Magic sets per year, and 2 Horizons/Remastered type sets per year. You can’t really pump a set shorter than 6 weeks, and it seems like 8 or 9 sets is the upper bound on what they can release each year.
Going down to 3 Standard-legal sets will be weird, unless they plan to push UB into Standard.
@meant2live218 @mike maybe 3 standard sets plus the permanent standard set that they announced would work. If that's just 200 or so evergreen standard cards it would provide that extra bump
