The most surprising exceptions
A closer look at the deckbuilding rules these commanders bend the furthest.
You may run Angel creature cards of any color identity, and any basic land cards, in a deck whose color identity is otherwise white.
Instant and sorcery cards in your deck may include one additional color of your choice outside blue, and you may run any basic lands.
You may run Aura cards of any color identity, and any basic lands. The Unluckiest Planeswalker can be your commander.
You may run any land cards, including nonbasic and color-producing lands of any type, in a red-green deck.
How Rulebreaker Works
One rule, broken cleanly
Rulebreaker is an ability word that lets each commander bend exactly one Commander deckbuilding rule.
Rulebreaker is an ability word
Rulebreaker has no rules meaning on its own. The italic word groups abilities with a shared theme. The ability text that follows it defines each commander's exception; that text is not ability text.
It only applies while the card is your commander
A Rulebreaker exception is active only when that card is your commander. The same card in the 99 (or anywhere else) grants no deckbuilding exception.
It changes deckbuilding, not gameplay
The exception is a pregame deckbuilding rule. It does not change a card's color identity, and it has no effect on how spells and abilities work during the game.
Each commander breaks one specific rule
Every Rulebreaker commander bends exactly the restriction its ability text names — a card category, a color, or a deck-size rule. No Rulebreaker removes all Commander restrictions.
Governed by the Commander rules
Commander deck construction is defined by the Comprehensive Rules (section 903). Rule 903.5e governs the pregame deckbuilding exception that Rulebreaker commanders rely on. The official sources below are authoritative.
FAQ
Frequently asked questions
Practical answers about color identity, deck size, commander requirements, and format legality.
What is the Rulebreaker mechanic?
Rulebreaker is an ability word on eight legendary cards from Mystery Booster Commander Edition. Each one lets its deck ignore one specific Commander deckbuilding restriction while that card is your commander.
Does Rulebreaker change a commander's color identity?
No. A Rulebreaker exception is a deckbuilding rule only. It does not change the commander's color identity, and it does not affect the game once it begins.
Does a Rulebreaker remove all Commander restrictions?
No. Each Rulebreaker commander bends only the exact restriction its ability text names. The singleton rule, the banned list, and all other Commander rules still apply.
Do these commanders break the singleton rule or banned list?
No. Rulebreaker exceptions never change the singleton rule or the Commander banned list. They only modify the specific deckbuilding category described on each card.
What does "Phyrexian" mean on Valko Indorian?
It refers to the Phyrexian creature type — cards with Phyrexian in their type line — not to cards that merely use Phyrexian mana symbols.
What does Grizzlegom's "any land cards" mean?
Unlike the other exceptions (which say "any basic land cards"), Grizzlegom, Hurloon Hero allows any land cards at all — including nonbasic and utility lands of any color.
Are Mystery Booster Commander Edition cards Commander-legal?
New-to-Magic cards from Mystery Booster Commander Edition become Commander-legal on November 13, 2026. Cards reprinted from other sets use their existing format legality.
How many Rulebreaker commanders are there?
Eight. Seluma, Light of Aysen; Tolabow, Loch Rascal; Valko Indorian; The Unluckiest Planeswalker; Maular, the Next Evolution; Grizzlegom, Hurloon Hero; Whtz, the Bibliophile; and The Everforger.
