Commander Rules, in Full

The dry, precise version: every deckbuilding and zone rule that governs a game of Commander, including the edge cases that decide real games.

A card’s color identity is every colored mana symbol printed anywhere on it — the classic gotcha that keeps off-color activations out of your 99.

Deckbuilding

Building the 100

Exactly 100 cards, one of everything, all inside your commander’s color identity.

Deck construction rules

  • Exactly 100 cards including your commander — not a 100-card minimum.
  • Singleton: one copy of every card except basic lands (and cards that explicitly break the rule, like Relentless Rats).
  • Every card must fit your commander’s color identity. A colorless commander restricts you to colorless cards and lands without off-color identity.
  • Your commander must be a legendary creature, or a card that explicitly says it can be your commander.

Lands have identity too

Color identity applies to lands. A deck with a mono-white commander cannot run a land with a black mana symbol in its rules text — basic land types in particular can smuggle identity onto unexpected cards.

02

The zone

Command zone mechanics

The command zone is why your strategy always shows up — and the tax is what keeps that honest.

Your commander begins the game in the command zone, face up, visible to every player. You may cast it from there as though it were in your hand, any time you could legally cast it. This guaranteed access is the format’s engine: your deck is built knowing its centerpiece always arrives.

The balancing mechanism is commander tax: each time you cast your commander from the command zone after the first, it costs {2} more for each previous time it was cast from there. A 4-mana commander costs 6 on its second trip, 8 on its third. The tax resets only when the game does.

EventDefault destinationCommand zone optionWhy it matters
DiesGraveyardReplace: return to command zoneSkipping the graveyard dodges reanimation but also death triggers
ExiledExileReplace: return to command zoneRemoval never deals with a commander permanently
BouncedHandStay in hand (no choice needed)Casting from hand avoids commander tax
Shuffled / libraryLibraryReplace: return to command zoneTucking a commander stopped being a hard answer in 2015
When your commander changes zones, you choose: let it go where the game sends it, or return it to the command zone.

Tax planning is real strategy

Bounce effects that return your commander to hand let you recast it without tax, and cost reducers apply to the whole taxed total. Good pilots budget the tax into their game plan from turn one.

03

Identity

Color identity edge cases

Identity is defined by printed mana symbols, not by how a card behaves — which produces some famous surprises.

Card name · mana cost {1}{W}{B}Identity
Art
Type line · color indicator dot on some double-faced cardsIdentity
Rules text: “…pay {B} …” — symbols here count, even inside reminder textIdentity
Flavor text — never counts

A card’s color identity is every colored mana symbol printed anywhere on it — the classic gotcha that keeps off-color activations out of your 99.

Everywhere a color-identity symbol can hide on a card.

The cases that catch people

  • Reminder text counts — Extort’s “(you may pay {W/B}…)” gives a card white-black identity even though the mechanic works in any deck.
  • Color indicators count — the back faces of some double-faced cards carry identity with no mana symbols in their cost.
  • Activation and ability costs count — a colorless artifact with a red activated ability has red identity.
  • Flavor text and card names never count, and neither does a card’s rules-of-the-game color (devoid cards are colorless but their symbols still set identity).
04

Variants in the zone

Partners, backgrounds, and companions

Several mechanics put more than one card in your command zone — each with its own wrinkles.

The high-level picture

  • Partner — two commanders that each have the partner ability; your color identity is their union, and each accrues commander tax separately.
  • Partner with X — paired cards that can only partner with their named counterpart.
  • Backgrounds — a “Choose a Background” commander pairs with a Background enchantment that lives in the command zone like a second commander.
  • Companions sit outside both the 100 and the command zone — they impose a deckbuilding restriction and can be put into hand once per game.

Keep it high level at the table

The full comprehensive-rules text for these mechanics runs long. For casual play, the union-of-identities rule and separate tax tracking cover almost every real situation.

05

At the table

Mulligans and multiplayer structure

Free-for-all multiplayer changes the frame around the rules you already know.

Conventions and structure

  • Mulligans: multiplayer games commonly grant one free mulligan, then London mulligan rules apply. Confirm the table’s convention before drawing.
  • Turn order proceeds clockwise; each player takes a full normal turn. With four players, expect real downtime — play at instant speed where you can.
  • Combat is one-at-a-time: you declare attacks against specific players (or their planeswalkers/battles); 21 combat damage from a single commander eliminates a player regardless of life total.
  • When a player loses, everything they own leaves the game. Effects they controlled end.
  • The last player standing wins — though plenty of games end with a combo, an alternate win condition, or a concession-inducing board state first.

Commander damage is per commander

Track combat damage from each commander separately — 11 from one commander and 10 from another does not eliminate you. Only 21 from the same commander does, and general life loss still applies normally.

FAQ

Common questions

Does commander tax reset if my commander dies?
No. The tax counts how many times you have cast your commander from the command zone this game, and nothing short of the game ending resets it. Returning it to hand and casting it from there is the classic way around the tax.
Can I put my commander in the graveyard instead of the command zone?
Yes — the command zone return is optional. Sometimes the graveyard is better: reanimation, death triggers, or escaping the tax. You choose as the zone change happens (or as a state-based action for death/exile).
Why can’t my Esper deck run a card with a red symbol in its reminder text?
Color identity counts every colored mana symbol printed on the card, including reminder text. It is a deckbuilding rule, not a gameplay rule — the card never needs to be cast for its identity to matter.
