Commander is a multiplayer Magic format in which each player builds a 100-card deck around a single legendary creature, uses only one copy of every card other than basic lands, and starts the game at 40 life. Wizards of the Coast describes it as the most popular way to play Magic in the world, and the design of the format explains why: cards never rotate out, every deck is built around a character you chose, and no two games play out the same way.
This guide covers the rules as they currently stand, the bracket system that governs pre-game conversations, and the honest reasons the format displaced two-player constructed as the default at most tables.
That colour-identity rule is the one new players get wrong. A card with a green mana symbol buried in an activated ability is a green card for this purpose, regardless of what its casting cost looks like.
Commander-ness is a property of the physical card, not a characteristic. It cannot be copied or overwritten, and a commander stolen by another player is still a commander.
With three or more players it is a free-for-all: seating is random, turns go clockwise, and you may attack any player at any point regardless of where they sit. Wizards lists the format at three to five players and roughly 20 minutes of game time per player, which is why a four-person pod runs to about two hours.
This changed recently and is worth knowing. Commander was maintained for years by an independent Rules Committee. Since late September 2024, the format has been managed by Wizards of the Coast's game design team together with the Commander Format Panel, a group of community members who publish periodic updates and banned-list announcements.
The practical effect is that the banned list, the bracket system and the Game Changers list all now live on magic.wizards.com. If you are checking legality, check there.
Commander's biggest structural problem is that "casual multiplayer" covers everything from a themed deck built around a favourite character to a tuned competitive list. Two people can both be honestly playing Commander and have a miserable game together.
The bracket system exists to fix that. There are five brackets:
| Bracket | Name | Game Changers allowed |
|---|---|---|
| 1 | Exhibition | None |
| 2 | Core | None |
| 3 | Upgraded | Up to three |
| 4 | Optimized | Unlimited |
| 5 | cEDH | Unlimited |
Brackets 1 to 3 describe different levels of socially focused play; 4 and 5 describe higher-power and competitive play. Each bracket also carries expectations around two-card infinite combos, extra turns and mass land denial.
The Game Changers list is the one hard restriction in the system — a curated set of cards judged capable of warping a game badly enough that other players would reasonably want to know in advance. Farewell and Biorhythm were added in the February 2026 update, with Lutri, the Spellchaser explicitly excluded on the grounds that it was never banned for raw power.
Two things the Commander Format Panel has repeatedly stressed: brackets are a tool to guide a conversation, not a gate on who may play whom — Bracket 2 against Bracket 3 games are often fine — and Bracket 1 is explicitly a space where stretching card legality, including Un-cards, is acceptable if the table agrees. The system remains formally in beta as of the February 2026 update.
Four reasons, in rough order of importance.
Cards do not rotate. A card you buy for a Commander deck is legal indefinitely. In Standard, six sets leave the format every year. For anyone who plays occasionally rather than weekly, that difference is decisive.
Singleton flattens the cost curve. You need one copy of a card, not four. A deck that would be prohibitive in a four-of format is reachable in Commander.
It is social by construction. Four players at a table is a different evening from two players across a table. Games are longer, politics matter, and losing is less abrupt.
Every deck is a statement. You pick a commander and the deck follows. That is a more engaging brief than "build the best 60 cards".
Wizards has been candid that this popularity created its own problem: a format built for one kind of experience is now being asked to serve everything from thematic casual play to cEDH. The brackets are the response to that, and the Commander Format Panel has said it expects to slow the rate of change rather than keep tuning.
Buy a preconstructed Commander deck rather than building from scratch. They are legal out of the box, come with a ready-made mana base, and give you a working list to modify one card at a time. Note that Wizards decoupled preconstructed decks from Bracket 2 in its October 2025 update — a precon is no longer automatically a Bracket 2 deck, so it is still worth reading the list.
Upgrade with singles rather than packs. Because Commander is singleton, one copy of a card finishes the job, and buying that single is far more direct than opening product hoping for it. We keep preconstructed decks and sealed product in MTG sealed, and carry other games on the other TCGs page.
If you want a starting point matched to a group you already play with, tell us what they run — matching a first Commander deck to an existing pod is a more useful conversation than matching it to a colour you like the look of.
Wizards lists the format at three to five players, with four being the standard pod size. Two-player Commander is played, but the format's rules — particularly the 40 starting life and the free-for-all attack structure — are built around multiplayer.
A player who has been dealt 21 or more combat damage by the same commander over the course of a game loses, regardless of their life total. This is tracked across zone changes, and continues to count even if another player takes control of that commander.
Each time you cast your commander from the command zone after the first, it costs an additional two generic mana. This is cumulative, so a commander cast for the third time costs four extra generic mana.
No. Commander has no rotation, which is one of the main reasons it overtook rotating formats in popularity. Cards are removed only through the format's banned list, which is now maintained by Wizards of the Coast with the Commander Format Panel.
No. Brackets are an optional tool to guide the pre-game conversation, and the Commander Format Panel has been explicit that they are not an arbiter of who may play whom. Games across adjacent brackets are common and usually fine.
