Mystery Booster Commander Legality: Full Format Breakdown

Mystery Booster Commander legality splits across two dates. Commander legality lands November 13 at MagicCon Atlanta. Legacy and Vintage don't get these cards until January 1, 2027, and Wizards has a supply-chain reason for the gap. This breaks down what's legal where, what stays banned no matter what, and why Standard, Pioneer, and Modern players never see this set at all.

MTGs MSCHF Zeta Set booster packs launch September 2 as Secret Lair's first randomized booster product. Each $19.92 pack has a shot at cards like Chrome Mox and Urborg, Tomb of Yawgmoth, and it's not print-to-demand like the recent Miku drop, so nobody knows the print run.

Riftbound has posted the same kind of numbers Lorcana did back in 2023, and Yu-Gi-Oh before that. Should MTG be afraid of Riftbound eating into its player base, or is this a cycle Magic has already lived through more than once? This breaks down how fast Riftbound actually grew, what it does differently from Magic, why most industry voices don't see it as a genuine threat, and the real structural lesson Magic should be taking from it regardless.
