The Commander Bracket System

For most of Commander’s life, matching decks of similar strength relied on fuzzy self-assessment: “it’s a 7” meant something different at every table. In February 2025, Wizards of the Coast and the Commander Format Panel introduced the bracket system as a beta — a five-step scale with concrete deckbuilding criteria, so a number actually communicates something.

Adoption was fast: in WotC’s official survey from MagicCon Chicago, 87% of players who tried the system said it helped them find an appropriately powered match. The system has been refined since launch — most notably in the October 21, 2025 update — and remains in beta through 2026, with the February 9, 2026 update keeping the bracket structure itself untouched.

Game Changers are cards WotC and the Format Panel judge to push games toward earlier, more lopsided endings — fast mana, mass land destruction enablers, hard locks, and the most efficient tutors and engines. Brackets 1 and 2 run none; Bracket 3 may include up to three; Brackets 4 and 5 are unrestricted.

The list is explicitly a living document. It launched at exactly 40 cards; the April 2025 update grew it to 61 (18 cards added, two removed, and five newly unbanned cards joining the list); on October 21, 2025 ten cards came off while the separate tutor restrictions were dropped entirely; and the February 9, 2026 update added Farewell and the newly unbanned Biorhythm. Because it moves, treat any specific count you read — including this one — as a snapshot.
