Each Commander bracket describes a kind of deck. A Bracket 1 (Exhibition) deck prioritizes a goal, theme or idea over power. A Bracket 2 (Core) deck is unoptimized and straightforward, runs no Game Changers, and wins incrementally, in ways the whole table can see coming. A Bracket 3 (Upgraded) deck is powered up with strong synergy and high card quality, plus up to three Game Changers. A Bracket 4 (Optimized) deck is lethal, consistent and fast, with no limit on Game Changers. A Bracket 5 (cEDH) deck is meticulously designed for competitive play.
Those descriptions follow the Commander Format Panel's own wording. Game Changers are the cards on the Panel's list, cards that "can dramatically warp Commander games", 53 of them as of October 2026. Here's what each bracket looks like in an actual list, starting with the 2026 precons.
Bracket 2 (Core): the 2026 precons
Core, first described in Introducing Commander Brackets Beta and rewritten in the Panel's October 21, 2025 update, asks for no Game Changers, no intentional two-card infinite combos and no mass land denial, and for extra-turn cards only in low quantities, never chained. Games usually last at least eight turns. As of October 23, 2026, our bracket checker reads all eleven 2026 precons from Lorwyn Eclipsed, Secrets of Strixhaven and Marvel Super Heroes as Bracket 2 (Core), and not one of them contains a Game Changer.
| Deck | Released | Commander | Colours |
|---|---|---|---|
| Blight Curse | January 23 | Auntie Ool, Cursewretch | Black, red, green |
| Dance of the Elements | January 23 | Ashling, the Limitless | All five |
| Lorehold Spirit | April 24 | Quintorius, History Chaser | Red, white |
| Prismari Artistry | April 24 | Rootha, Mastering the Moment | Blue, red |
| Quandrix Unlimited | April 24 | Zimone, Infinite Analyst | Green, blue |
| Silverquill Influence | April 24 | Killian, Decisive Mentor | White, black |
| Witherbloom Pestilence | April 24 | Dina, Essence Brewer | Black, green |
| Avengers Assemble | June 26 | Captain America, Team Leader | Red, blue, white |
| Doom Prevails | June 26 | Doctor Doom, King of Latveria | Blue, black, red |
| The Fantastic Four | June 26 | Invisible Woman | Green, red, blue, white |
| Wakanda Forever | June 26 | T'Challa, the Black Panther | Green, white |
What the eleven share is a good picture of Core. Every one runs 37 to 40 lands and includes Sol Ring, Arcane Signet and Command Tower, and Sol Ring stays off the Game Changers list on purpose: in the Panel's words, every deck "gets exactly one Sol Ring".
What they don't share is speed. Quandrix Unlimited averages 2.39 mana value across its nonland cards and has no card at six or higher, while Dance of the Elements averages 4.27 with sixteen cards at six or more. Both are Core decks: a curve changes how a game plays out, but the bracket turns on what a deck leaves out and how quickly it means to win.
Looking for the best Core deck to start with? Our precon ranking picks Quandrix Unlimited as the easiest to pilot and Witherbloom Pestilence as the easiest to upgrade. Just don't mistake the box for the bracket: since the October 21, 2025 update, a precon is no longer the official reference point for any bracket, so a precon from another year deserves its own check.
Bracket 3 (Upgraded): a precon plus up to three Game Changers
Bracket 3 is the first bracket that lets Game Changers in, and the official format page sets the number: "Bracket 3 allows for up to three Game Changers." That means three different cards, since a Commander deck runs one copy of each card other than basic lands (Comprehensive Rules 903.5b). The Panel expects them to be "value engines and game-ending spells", in games that usually last at least six turns.
The simplest Bracket 3 deck is a Core deck with its first Game Changers in. Swap one, two or three into any precon above, inside its commander's colour identity (Comprehensive Rules 903.5c), and our bracket checker reads the list as Bracket 3 (Upgraded), as long as nothing else on it points higher; the example list in the checker with Rhystic Study as its only Game Changer reads exactly that.
Value engines are the natural first picks. Rhystic Study and Smothering Tithe turn your opponents' spells and draws into cards and Treasure unless they pay up, and The One Ring, if you cast it, gives you protection from everything until your next turn when it enters, then draws you one more card each time you tap it, at a growing cost in life each upkeep. Big resets live here too: the Panel added Farewell in February 2026 at "Bracket 3 and above", so that people "get into games that could have a Farewell only if they want to". A commander on the list, such as Tergrid, God of Fright, fills one of the three slots on its own. In the deck builder, Scry, our card search, can show only Game Changers, which makes picking your three quick.
The ten-card swap in our upgrade guide is a different kind of upgrade. It gives Blight Curse a signet, two ramp spells, card draw, removal, a board wipe, a recursion spell and a utility land, and none of those ten is a Game Changer, so the deck gets far more consistent while its Game Changer count stays at zero. An upgraded precon isn't automatically an Upgraded deck: what moves the checker's reading is which cards you add, not how many you swap, though a deck that now plays much stronger is worth a word with your pod.
Bracket 4 (Optimized): what pushes a deck there
Bracket 4 Commander decks are lethal, consistent and fast, designed to take people down as quickly as possible, and games usually last at least four turns. There's no cap on Game Changers. Four things in a list point here, and our bracket checker looks for all of them:
| What the list contains | Why it points to Bracket 4 | Who draws the line |
|---|---|---|
| Four or more Game Changers | Bracket 3 allows up to three | Published policy |
| Any mass land denial card, such as Armageddon | Brackets 1 to 3 expect none | Published policy |
| Both halves of a two-card combo the checker knows | Bracket 3 allows no two-card infinite combo that comes together cheaply and early | Mana Grove's reading |
| Three or more different extra-turn cards | Brackets 2 and 3 allow a few, never chained | Mana Grove's reading |
Published policy is the Panel's own line; Mana Grove's reading is where the policy names no number, or gives no way to judge from a list, so our checker makes the call and says so.
Two of the example lists you can load in the checker show both kinds. "Four Game Changers" holds Rhystic Study, Cyclonic Rift, Smothering Tithe and The One Ring, and reads Bracket 4 on the count alone. "A two-card combo" is the one worth a second look: neither Heliod, Sun-Crowned nor Walking Ballista is a Game Changer, and neither counts for anything alone, but together they make a combo the checker knows, so it answers Bracket 4 as its own reading. The October 2025 update explains why: "If a combo could frequently come up, it's not the best fit for that bracket." Want to keep a combo like that in a Bracket 3 deck? Raise it before the game.
All four set a floor, not a ceiling. A list with none of them can still play like Bracket 4 if it's built to win fast, and the October 2025 update admits as much: "I can easily build a deck which technically fits the restrictions of Bracket 2 but can play at a very high power level."
Bracket 5 (cEDH): built for the competitive metagame
Bracket 5 plays by the same card rules as Bracket 4: any number of Game Changers, and none of the limits the lower brackets put on combos, extra turns and land denial. What separates the two is purpose. Bracket 5 decks are "meticulously designed to battle in the cEDH metagame", the field of competitive decks they expect to face, and a game against one could end on any turn. Bracket 4 is about how strong a deck is; Bracket 5 is about what it's built to beat.
Purpose doesn't show up in a card count, which is why our bracket checker stops at Bracket 4. A list that reads Bracket 4 might be a cEDH deck, and only the player who built it can say so.
Bracket 1 (Exhibition): theme over power
Bracket 1 is the other bracket no list can show. An Exhibition deck prioritizes a goal, theme or idea over power, its win conditions are highly thematic or substandard, and games usually last at least nine turns. Officially it runs no Game Changers, but it isn't simply the weakest bracket, and the October 2025 update is blunt about it: "A deck is not Bracket 1 based on power level alone."
It's also the most flexible bracket at the table. The Panel calls it "a place where stretching the rules of card legality is okay" when everyone agrees before the game, and it says a highly thematic Game Changer, such as Bolas's Citadel in a Bolas-themed deck, belongs in that pre-game conversation. Our checker sees only the card and reads that list as Bracket 3, which is exactly why Bracket 1 is yours to declare.
How to move a deck between brackets
Moving up is mostly about Game Changers. From Core to Upgraded, swap in one to three. From Upgraded to Optimized, a fourth will do it, and so will a mass land denial card, an early two-card combo or a chain of extra turns.
Moving down is the same list in reverse: three Game Changers at most for Bracket 3 and none for Bracket 2, no mass land denial below Bracket 4, no two-card combo with both halves in the deck unless your pod has agreed to it, and extra-turn cards kept few and never chained. Our bracket checker guide walks through it under "Moving a deck down a bracket", and the bracket checker tells you when the list gets there.
Either way, the number you get back is a floor. The bracket you declare also covers intent and speed, and the Panel's own example is still the best way to say it: "I'm in Bracket 2, except for this one thing. Is that okay with everybody?" Commander brackets explained covers that conversation.
Frequently asked questions
Which Commander decks fit each bracket?
The eleven 2026 precons in the table above read as Bracket 2 (Core) in our bracket checker as they come out of the box, one to three Game Changers move the same lists to a Bracket 3 reading, and a fourth Game Changer, a mass land denial card, an early two-card combo or chained extra turns gives a Bracket 4 reading. Bracket 5 is for decks built to beat the competitive cEDH metagame and Bracket 1 for theme decks that put an idea ahead of power; no decklist shows either, so you declare those two, and the sections above show what a deck in each looks like.
Is a precon Bracket 2?
Not automatically any more. The Panel used the average current precon as Core's reference point until its October 21, 2025 update, which dropped it. As of October 23, 2026, our bracket checker reads all eleven ranked 2026 precons as Bracket 2 (Core), with no Game Changer in any of them. Judge any other precon by its list, not its box.
Can a precon be Bracket 3?
Yes. When the Panel dropped the precon reference point, it said some modern precons fit Bracket 3 better. A precon with one to three Game Changers in it reads at least Bracket 3 in our checker unless something else in it points higher, and one with none can still play like an Upgraded deck, a call for your pod rather than a count.
How do I move a deck from Bracket 2 to Bracket 3?
Swap in one to three Game Changers that fit your commander's colour identity. Each will be a different card, since a Commander deck runs one copy of each card other than basic lands (Comprehensive Rules 903.5b). Keep the rest of the list free of mass land denial, early two-card combos and chained extra turns, any of which points to Bracket 4. Then tell your pod what changed.
What is the difference between Bracket 4 and Bracket 5?
Both allow any number of Game Changers. Bracket 4 (Optimized) decks are lethal, consistent and fast; Bracket 5 (cEDH) decks are "meticulously designed to battle in the cEDH metagame". The difference is purpose rather than card count, so our checker never answers Bracket 5 and leaves that call to you and your pod.
Build the deck for the bracket you want
In the Mana Grove deck builder, set a Target bracket on your deck and the Bracket signals panel counts your Game Changers and flags mass land denial, extra turns, fast mana and tutors, so you see a list drift up a bracket before your pod does. Rather start from a sentence? Tell Grover, our AI deck assistant, the bracket in your brief, such as "Bracket 2, no infinite combos", and set the deck builder's Target bracket to the same value, which sends it to Grover with the build. Both the deck builder and Grover open without an account. Create a free account when you're ready; every plan includes the full deck builder, and plans and pricing shows what the paid plans add.
