Règles complètes de Magic: The Gathering

715.1.

One card (Shahrazad) allows players to play a Magic subgame.

715.1a

A «subgame» is a completely separate Magic game created by an effect. Essentially, it‘s a game within a game. The «main game» is the game in which the spell or ability that created the subgame was cast or activated. The main game is temporarily discontinued while the subgame is in progress. It resumes when the subgame ends.

715.1b

No effects or definitions created in either the main game or the subgame have any meaning in the other, except as defined by the effect that created the subgame. For example, the effect may say that something happens in the main game to the winner or loser of the subgame.

715.2.

As the subgame starts, an entirely new set of game zones is created. Each player takes all the cards in his or her main-game library, moves them to his or her subgame library, and shuffles them. No other cards in a main-game zone are moved to their corresponding subgame zone, except as specified in rules 715.2a–d. Randomly determine which player goes first. The subgame proceeds like a normal game, following all other rules in rule 103, «Starting the Game.»

715.2a

As a subgame of a Planechase game starts, each player moves his or her planar deck from the main-game command zone to the subgame command zone and shuffles it. (Face-up plane cards remain in the main-game command zone.)

715.2b

As a subgame of a Vanguard game starts, each player moves his or her vanguard card from the main-game command zone to the subgame command zone.

715.2c

As a subgame of a Commander game starts, each player moves his or her commander from the main-game command zone (if it‘s there) to the subgame command zone.

715.2d

As a subgame of an Archenemy game starts, the archenemy moves his or her scheme deck from the main-game command zone to the subgame command zone and shuffles it. (Face-up scheme cards remain in the main-game command zone.)

715.3.

Because each player draws seven cards when a game begins, any player with fewer than seven cards in his or her deck will lose the subgame when state-based actions are checked during the upkeep step of the first turn, regardless of any mulligans that player takes. (See rule 704, «State- Based Actions.»)

715.4.

All objects in the main game and all cards outside the main game are considered outside the subgame (except those specifically brought into the subgame). All players not currently in the subgame are considered outside the subgame.

715.4a

Some effects can bring cards into a game from outside of it. If a card is brought into a subgame from a main game, abilities in the main game that trigger on objects leaving a maingame zone will trigger, but they won‘t be put onto the stack until the main game resumes.

715.5.

At the end of a subgame, each player takes all cards he or she owns that are in the subgame other than those in the subgame command zone, puts them into his or her main-game library, then shuffles them. This includes cards in the subgame‘s exile zone. Except as specified in rules 715.5a– c, all other objects in the subgame cease to exist, as do the zones created for the subgame. The main game continues from the point at which it was discontinued: First, the spell or ability that created the subgame finishes resolving, even if it was created by a spell card that‘s no longer on the stack. Then, if any main-game abilities triggered while the subgame was in progress due to cards being removed from the main game, those abilities are put onto the stack. Example: If a card was brought into the subgame either from the main game or from outside the main game, that card will be put into its owner?s main-game library when the subgame ends.

715.5a

At the end of a subgame of a Planechase game, the face-up plane card is turned face down and put on the bottom of its owner‘s planar deck. Then each player moves his or her planar deck from the subgame command zone to the main-game command zone and shuffles it.

715.5b

At the end of a subgame of a Vanguard game, each player moves his or her vanguard card from the subgame command zone to the main-game command zone.

715.5c

At the end of a subgame of a Commander game, each player moves his or her commander from the subgame command zone (if it‘s there) to the main-game command zone.

715.6.

A subgame can be created within a subgame. The existing subgame becomes the main game in relation to the new subgame.
