A player still in the game wins the game if all of that player's opponents have left the game. This happens immediately and overrides all effects that would prevent that player from winning the game.

Effects can add or remove abilities of objects. An effect that adds an ability will state that the object "gains" or "has" that ability. An effect that removes an ability will state that the object "loses" that ability. Effects that remove an ability remove all instances of it. If two or more effects add and remove the same ability, in general the most recent one prevails. (See rule 613, "Interaction of Continuous Effects.")

The converted mana cost of a double-faced permanent's back face is calculated as though it had the mana cost of its front face. This is a change from previous rules. If a permanent is a copy of the back face of a double-faced card (even if the card representing that copy is itself a double-faced card), the converted mana cost of that permanent is 0.

Example: Huntmaster of the Fells is a double-faced card with mana cost {2}{R}{G}. Its converted mana cost is 4. After it transforms to its other face (Ravager of the Fells), its converted mana cost remains 4.

Example: A Clone enters the battlefield as a copy of Ravager of the Fells. Its converted mana cost is 0.

Example: Insectile Aberration is the back face of a double-faced card whose front face has mana cost {U}. It becomes a copy of Ravager of the Fells. Its converted mana cost becomes 0.

If text states that a player may do something "any time he or she could cast an instant," it means only that the player must have priority. The player doesn't need to have an instant he or she could actually cast. Effects that would prevent that player from casting a spell or casting an instant don't affect the player's capability to perform that action (unless the action is actually casting a spell or casting an instant).

If a player controls two or more planeswalkers that share a planeswalker type, that player chooses one of them, and the rest are put into their owners' graveyards. This is called the "planeswalker uniqueness rule." See rule 704.

Previously, planeswalkers were subject to a "planeswalker uniqueness rule" that stopped a player from controlling two planeswalkers of the same planeswalker type. This rule has been removed and planeswalker cards printed before this change have received errata in the Oracle card reference to have the legendary supertype. Like other legendary permanents, they are subject to the "legend rule" (see rule 704.5j).

If a spell, ability, or effect states that a player can do something only "any time he or she could cast a sorcery," it means only that the player must have priority, it must be during the main phase of his or her turn, and the stack must be empty. The player doesn't need to have a sorcery he or she could actually cast. Effects that would prevent that player from casting a spell or casting a sorcery don't affect the player's capability to perform that action (unless the action is actually casting a spell or casting a sorcery).

Abilities of Auras that trigger when the enchanted permanent leaves the battlefield can find the new object that Aura became in its owner's graveyard if it was put into that graveyard at the same time the enchanted permanent left the battlefield. It can also find the new object that Aura became in its owner's graveyard as a result of being put there as a state-based action for not being attached to a permanent. (See rule 704.5n.)

The active player checks each creature he or she controls to see whether it's affected by any requirements (effects that say a creature must attack, or that it must attack if some condition is met). If the number of requirements that are being obeyed is fewer than the maximum possible number of requirements that could be obeyed without disobeying any restrictions, the declaration of attackers is illegal. If a creature can't attack unless a player pays a cost, that player is not required to pay that cost, even if attacking with that creature would increase the number of requirements being obeyed.

Example: A player controls two creatures: one that "attacks if able" and one with no abilities. An effect states "No more than one creature can attack each turn." The only legal attack is for just the creature that "attacks if able" to attack. It's illegal to attack with the other creature, attack with both, or attack with neither.

If a creature can't attack unless a player pays a cost, that player is not required to pay that cost, even if attacking with that creature would increase the number of requirements being obeyed. If a requirement that says a creature attacks if able during a certain turn refers to a turn with multiple combat phases, the creature attacks if able during each declare attackers step in that turn.

Example: A player controls two creatures: one that "attacks if able" and one with no abilities. An effect states "No more than one creature can attack each turn." The only legal attack is for just the creature that "attacks if able" to attack. It's illegal to attack with the other creature, attack with both, or attack with neither.

The defending player checks each creature he or she controls to see whether it's affected by any requirements (effects that say a creature must block, or that it must block if some condition is met). If the number of requirements that are being obeyed is fewer than the maximum possible number of requirements that could be obeyed without disobeying any restrictions, the declaration of blockers is illegal. If a creature can't block unless a player pays a cost, that player is not required to pay that cost, even if blocking with that creature would increase the number of requirements being obeyed.

Example: A player controls one creature that "blocks if able" and another creature with no abilities. If a creature with menace attacks that player, the player must block with both creatures. Having only the first creature block violates the restriction created by menace (the attacking creature can't be blocked except by two or more creatures). Having only the second creature block violates both the menace restriction and the first creature's blocking requirement. Having neither creature block fulfills the restriction but not the requirement.

Because they aren't cast or activated, triggered abilities can trigger even when it isn't legal to cast spells and activate abilities. Effects that prevent abilities from being activated don't affect them.

Because they aren't cast or activated, triggered abilities can trigger even when it isn't legal to cast spells and activate abilities. Effects that preclude abilities from being activated don't affect them.

An activated ability is a mana ability if it meets all of the following criteria: it doesn't have a target, it could put mana into a player's mana pool when it resolves, and it's not a loyalty ability. (See rule 606, "Loyalty Abilities.")

An activated ability is a mana ability if it meets all of the following criteria: it doesn't have a target, it could add mana to a player's mana pool when it resolves, and it's not a loyalty ability. (See rule 606, "Loyalty Abilities.")

A triggered ability is a mana ability if it meets all of the following criteria: it doesn't have a target, it triggers from the resolution of an activated mana ability (see rule 106.11a), and it could put mana into a player's mana pool when it resolves.

A triggered ability is a mana ability if it meets all of the following criteria: it doesn't have a target, it triggers from the resolution of an activated mana ability (see rule 106.11a) or from mana being added to a player's mana pool, and it could add mana to a player's mana pool when it resolves.

Some replacement effects modify how a permanent enters the battlefield. (See rules 614.1c-d.) Such effects may come from the permanent itself if they affect only that permanent (as opposed to a general subset of permanents that includes it). They may also come from other sources. To determine which replacement effects apply and how they apply, check the characteristics of the permanent as it would exist on the battlefield, taking into account replacement effects that have already modified how it enters the battlefield (see rule 616.1), continuous effects generated by the resolution of spells or abilities that changed the permanent's characteristics on the stack (see rule 400.7a), and continuous effects from the permanent's own static abilities, but ignoring continuous effects from any other source that would affect it.

Example: Voice of All says "As Voice of All enters the battlefield, choose a color" and "Voice of All has protection from the chosen color." An effect creates a token that's a copy of Voice of All. As that token is created, the token's controller chooses a color for it.

Example: Yixlid Jailer says "Cards in graveyards lose all abilities." Scarwood Treefolk says "Scarwood Treefolk enters the battlefield tapped." A Scarwood Treefolk that's put onto the battlefield from a graveyard enters the battlefield tapped.

Example: Orb of Dreams is an artifact that says "Permanents enter the battlefield tapped." It won't affect itself, so Orb of Dreams enters the battlefield untapped.

Some effects state that something can't happen. These effects aren't replacement effects, but follow similar rules.

If an event can't happen, a player can't choose to pay a cost that includes that event.

If an event can't happen, a player can't choose to pay a cost that includes that event.

If an event can't happen, it can only be replaced by a self-replacement effect (see rule 614.15). Other replacement and/or prevention effects can't modify or replace it.

Neither activating an ability that creates a regeneration shield nor casting a spell that creates a regeneration shield is the same as regenerating a permanent. Effects that say that a permanent can't be regenerated don't prevent such abilities from being activated or such spells from being cast; rather, they prevent regeneration shields from having any effect.

Neither activating an ability that creates a regeneration shield nor casting a spell that creates a regeneration shield is the same as regenerating a permanent. Effects that say that a permanent can't be regenerated don't preclude such abilities from being activated or such spells from being cast; rather, they cause regeneration shields to not be applied.

A player may planeswalk as the result of the "planeswalking ability" (see rule 901.8), because the owner of a face-up plane card or phenomenon card leaves the game (see rule 901.10), or because a phenomenon's triggered ability leaves the stack (see rule 704.5x). Abilities may also instruct a player to planeswalk.

Abilities may also instruct a player to planeswalk.

If an activated or triggered ability of a permanent that isn't a delayed triggered ability of that permanent tries to transform it, the permanent transforms only if it hasn't transformed since the ability was put onto the stack. If a delayed triggered ability of a permanent tries to transform that permanent, the permanent transforms only if it hasn't transformed since that delayed triggered ability was created. In either case, if the permanent has already transformed, the instruction to transform is ignored. This is a change from previous rules.

In either case, if the permanent has already transformed, the instruction to transform is ignored.

Giving first strike to a creature without it after combat damage has already been dealt in the first combat damage step won't prevent that creature from assigning combat damage in the second combat damage step. Removing first strike from a creature after it has already dealt combat damage in the first combat damage step won't allow it to also assign combat damage in the second combat damage step (unless the creature has double strike).

Removing first strike from a creature after it has already dealt combat damage in the first combat damage step won't allow it to also assign combat damage in the second combat damage step (unless the creature has double strike).

An Aura, Equipment, or Fortification that phased out directly will phase in attached to the object or player it was attached to when it phased out, if that object is still in the same zone or that player is still in the game. If not, that Aura, Equipment, or Fortification phases in unattached. State-based actions apply as appropriate. (See rules 704.5n and 704.5p.)

Players win and lose the game only as a team, not as individuals. If either player on a team loses the game, the team loses the game. If either player on a team wins the game, the entire team wins the game. If an effect would prevent a player from winning the game, that player's team can't win the game. If an effect would prevent a player from losing the game, that player's team can't lose the game.

Example: In a Two-Headed Giant game, a player controls Transcendence, which reads, in part, "You don't lose the game for having 0 or less life." If that player's team's life total is 0 or less, that team doesn't lose the game.

Example: In a Two-Headed Giant game, a player attempts to draw a card while there are no cards in that player's library. That player loses the game, so that player's entire team loses the game.
