Commander brackets explained
Last updated: October 7, 2026
Commander brackets are Wizards of the Coast's system for matching decks of similar power before a game starts. Every deck sits in one of five brackets, and the conversation at the table changes from "how strong is your deck, out of ten?" — a question nobody answers the same way — to "which bracket?", which has rules behind it.
The five brackets
- Bracket 1 — Exhibition. Theme first, winning second. Decks built around a joke, a flavour or a constraint. No Game Changers, no mass land destruction, no extra turns, no two-card combos.
- Bracket 2 — Core. Roughly where an unmodified preconstructed deck lands. No Game Changers, no mass land destruction, no chained extra turns, no two-card infinite combos. Games are long and interactive.
- Bracket 3 — Upgraded. A deck someone has tuned. Up to three Game Changers. Still no mass land destruction or chained extra turns, and two-card combos are expected to wait for the late game.
- Bracket 4 — Optimized. High power. No restrictions beyond the banned list — any number of Game Changers, fast mana, tutors and combos.
- Bracket 5 — cEDH. Competitive Commander, built for tournaments, where the metagame and not the theme decides every card.
Wizards revises the wording a few times a year. The shape above has held since the system launched; check the official announcement for the current fine print.
Game Changers do most of the sorting
The quickest test is a count. Game Changers are a published list of cards that warp games — Rhystic Study, Smothering Tithe, Cyclonic Rift, Demonic Tutor, The One Ring, Teferi's Protection and around fifty more. Zero puts a deck in bracket 1 or 2, one to three puts it in bracket 3, and four or more means bracket 4.
A strong deck with no Game Changers is not automatically bracket 2. The count is a floor, not a verdict — tutors, fast combos and how quickly the deck closes still matter, and the system expects players to be honest about intent.
Where a precon lands
Most current preconstructed decks are bracket 2 out of the box. The first round of upgrades usually keeps them there — better mana, more removal, more card draw — and the deck stays in bracket 2 until a Game Changer goes in. Our precon upgrade guide stays inside that line, and budget Commander staples lists the cards that make a deck better without moving it up.
Sol Ring is not a Game Changer, and neither is Arcane Signet. Ramp, removal and card draw are what bracket 2 and 3 decks are made of.
Using brackets well
- Say the bracket and the exceptions. "Bracket 3, two Game Changers, one combo that needs six mana" tells the table more than a number alone.
- Match the table, not the ceiling. A bracket 3 deck in a bracket 2 pod wins more and is invited back less.
- Build to a bracket on purpose. Decide where the deck should sit, then spend on the cards that make it good there — not on the cards that push it out.
