TLDR: the legend rule in one paragraph
If you control two or more legendary permanents with the same name, you choose one and put the rest into their owners’ graveyards. This is a state-based action called the legend rule. It does not use the stack, so nobody can respond between the duplicate permanent entering and your choice. You can keep either permanent; Magic does not care which entered first. The rule only compares legendary permanents controlled by the same player, so two opponents can each control a copy without a problem.
That is the table-ready answer. The interesting parts involve triggered abilities, copies, stolen permanents, commanders, and the occasional card whose rules text politely tells the legend rule to take the afternoon off.
The exact condition that causes a legend-rule conflict
Rule 704.5j of the Magic Comprehensive Rules applies when one player controls two or more legendary permanents with the same name. That sentence contains all three requirements: the objects must be permanents on the battlefield, they must be legendary, and they must have the same name. The same player must also control them.
| Question | What the legend rule checks |
|---|---|
| Where are the cards? | They must be permanents on the battlefield. |
| Who controls them? | One player must control two or more of them. |
| Are they legendary? | Each conflicting permanent must have the legendary supertype. |
| Do their names match? | They must have the same name under the game rules. |
| What happens? | That player keeps one and puts the others into their owners’ graveyards. |
Different legendary cards can coexist even when they represent the same character. You can control several legendary creatures named for Jace, Chandra, or another recurring character as long as their complete names differ. Shared creature types and planeswalker types do not matter. The rule compares names, not biographies.
Different printings of the same card still have the same name. Border treatment, artwork, set symbol, language, and collector number do not turn one named permanent into a different named permanent. Cards with interchangeable names are also treated as having the same name for rules purposes.
Legendary is a supertype, not a card type
“Legendary” is a supertype that can modify several permanent types. A legendary object might be a creature, artifact, enchantment, land, or planeswalker. If that terminology is the confusing part, ProxyKing’s explainer on whether legendary is a card type covers the distinction in more detail.
This also explains why a legendary card on the stack is not involved in a legend-rule conflict. While you are casting a legendary artifact or creature, it is a spell. It becomes a permanent only after it resolves and enters the battlefield. The same zone-dependent terminology appears in the broader question of when an artifact counts as a spell.
Legendary cards in a hand, library, graveyard, or exile do not conflict with a legendary permanent on the battlefield. A legendary spell on the stack does not conflict either. You may cast a second copy while controlling the first; the rule becomes relevant if the spell resolves and gives you two same-named legendary permanents.
When the legend rule happens
The legend rule is a state-based action. State-based actions are checked whenever a player would receive priority, including immediately after a spell or ability finishes resolving. They do not use the stack. If a second same-named legendary permanent enters under your control, the game checks state-based actions before any player receives priority. You choose one to keep during that check.
You cannot respond to the legend rule itself. Once the second permanent is on the battlefield, there is no priority window in which you can activate an ability, cast an instant, or sacrifice one of the permanents before making the required choice. “Hold on, before the legend rule…” is a familiar sentence, but it does not create a priority window by force of optimism.
You can act earlier. If your second legendary spell is still on the stack, players have normal opportunities to respond. You could sacrifice the legendary permanent already on the battlefield before the new spell resolves, for example. Once that spell resolves and the second permanent enters, the next legend-rule check comes before anyone can act again.
What happens to enter-the-battlefield and death triggers?
State-based actions do not interrupt a resolving spell or ability. If an effect puts multiple same-named legendary permanents onto the battlefield, all of them enter as instructed. Enter-the-battlefield abilities can trigger. After the effect finishes resolving, state-based actions are checked, you keep one permanent, and the others go to their owners’ graveyards. Only after that process are waiting triggered abilities put onto the stack.
Suppose you control a legendary creature and another copy enters with a useful enter-the-battlefield ability. The new copy enters and its ability triggers. You then choose which copy to keep. The triggered ability can still be put onto the stack afterward, even if you put the new copy into the graveyard. The source of a triggered ability does not normally need to remain on the battlefield once that ability has triggered.
A legendary creature put into a graveyard by the rule also dies, because “dies” means being put into a graveyard from the battlefield. Suitable dies and leaves-the-battlefield abilities can therefore trigger. The move is not a sacrifice and is not destruction, however. Indestructible and regeneration do not prevent it, and an ability that triggers specifically when a permanent is sacrificed will not trigger merely because the legend rule moved it.
You choose which permanent stays
The controller chooses one of the conflicting permanents and keeps it. The rule does not automatically preserve the oldest copy, the newest copy, the nontoken copy, or the version with the fanciest artwork. You can keep whichever one is strategically useful.
That choice can matter when the permanents differ in ways the legend rule does not examine. One might be tapped, damaged, enchanted, equipped, or carrying counters. They can still have the same name, but you decide which individual permanent survives the state-based action. If one has accumulated useful counters and the other just arrived, the older one may be the obvious choice. If the new one has a better attachment or is untapped, perhaps not.
Control matters more than ownership
The legend rule groups permanents by controller, not owner. If you and an opponent each control a legendary permanent with the same name, both remain on the battlefield. Nothing is wrong because no single player controls two of them.
A control-changing effect can alter that result. If you gain control of an opponent’s same-named legendary permanent while already controlling your own, you now control both. At the next state-based-action check, you choose one and the other is put into its owner’s graveyard. If you keep the stolen permanent and move your own, yours goes to your graveyard. If you keep yours, the stolen card returns to its actual owner’s graveyard.
How copies interact with the legend rule
Copy effects ordinarily copy a permanent’s name and legendary supertype because those are copiable values. If a Clone-style creature copies your legendary creature, you will usually control two legendary permanents with the same name. Before anyone receives priority, you choose one and put the other into its owner’s graveyard.
Token copies work the same way unless the effect changes relevant characteristics or provides an exception. For example, if Splinter Twin creates a token copy of an enchanted legendary creature, that token normally has the copied name and legendary supertype. The token enters, any applicable abilities trigger, and its controller then handles the legend-rule conflict.
An excess legendary token is put into the graveyard rather than disappearing directly from the battlefield. It later ceases to exist during another state-based-action check. Because it reached the graveyard from the battlefield, appropriate dies or leaves-the-battlefield abilities can still trigger.
Face-down permanents usually avoid this issue while face down. A face-down permanent normally has no name and no legendary supertype, so it generally cannot match another legendary permanent for the rule. Turning it face up can immediately create a conflict if you then control two legendary permanents with the same name.
Cards that switch off or modify the legend rule
Some cards explicitly create exceptions. Sakashima of a Thousand Faces says the legend rule does not apply to permanents you control. Its copy effect retains that ability, allowing its controller to keep same-named legendary permanents while the exception remains active.
Mirror Gallery uses the broader text, “The ‘legend rule’ doesn’t apply.” If the effect disappears, the game applies the legend rule during the next state-based-action check. Players who suddenly control conflicting legendary permanents then make the required choices.
Brothers Yamazaki has a much narrower exception. If exactly two permanents named Brothers Yamazaki are on the battlefield, the legend rule does not apply to them. “Exactly two” is doing real work there; this is not a general permission slip for an entire family reunion.
Always follow current Oracle text when a card appears to contradict a normal rule. Magic’s rules permit card text to create specific exceptions, and legendary-copy cards frequently rely on careful wording rather than a universal change to the legend rule.
How the legend rule works in Commander
Commander’s singleton deckbuilding restriction is separate from the legend rule. Singleton limits what you normally put into the deck. The legend rule governs permanents already on the battlefield. A Commander game can still produce duplicate legendary permanents through copies, token creation, control changes, or similar effects.
If your commander is put into the graveyard by the legend rule, it reaches the graveyard first. During the next applicable state-based-action check, its owner may move it from the graveyard to the command zone. This sequencing matters for abilities that care about a creature dying or a card entering a graveyard.
A card’s status as a commander also remains with it if it becomes a copy of another card or is face down. That designation does not itself make the object legendary, and it does not protect the object from a conflict created by its current characteristics. Commander status and the legendary supertype are related in deck construction, but they are not the same rules concept.
Common legend-rule mistakes
- Trying to respond after the duplicate permanent enters but before choosing one. State-based actions happen before priority is given.
- Assuming the newest permanent must go. Its controller may keep either one.
- Treating the move as destruction or sacrifice. It is neither, although a creature moved this way does die.
- Applying the rule across different players. Each player checks only the legendary permanents they control.
- Comparing character identity instead of card names. Different names can coexist, even when both cards depict the same character.
- Assuming singleton deck construction prevents duplicate permanents. Copies and control-changing effects can still create them during a game.
Adjacent rules that are not the legend rule
Legendary instants and sorceries are not removed by the legend rule because they are not permanents on the battlefield. They have a separate casting restriction: to cast a legendary instant or sorcery, you must control a legendary creature or legendary planeswalker. That restriction should not be confused with rule 704.5j.
The world rule is another separate state-based action. It handles permanents with the world supertype and follows its own conditions. “World” and “legendary” may both sound like labels reserved for important cardboard, but the game treats them as different rules systems.
The practical rule to remember
When duplicate legends appear, ask four questions in order: Are they permanents on the battlefield? Are they legendary? Do they have the same name? Does one player control both? If every answer is yes, that player keeps one and puts the rest into their owners’ graveyards before anyone receives priority.
For gameplay decisions, act before the second permanent resolves if you need a sacrifice or activated ability from the existing one. If you want value from entering or dying triggers, remember that those abilities can still trigger even though the legend-rule choice happens before they are put onto the stack. That timing distinction solves most legend-rule disputes without requiring the table to convene a small constitutional court.
