Comprehensive Rules

At the start of a game, the players determine which one of them will choose who takes the first turn. In the first game of a match (including a single-game match), the players may use any mutually agreeable method (flipping a coin, rolling dice, etc.) to do so. In a match of several games, the loser of the previous game chooses who takes the first turn. If the previous game was a draw, the player who made the choice in that game makes the choice in this game. The player chosen to take the first turn is the starting player. The game’s default turn order begins with the starting player and proceeds clockwise.

In a game using the shared team turns option, there is a starting team rather than a starting player.

In an Archenemy game, these methods aren’t used to determine who takes the first turn. Rather, the archenemy takes the first turn.

One card (Power Play) states that its controller is the starting player. This effect applies after this determination has happened and supersedes these methods.

Some games require additional steps that are taken after the starting player has been determined. Perform the actions listed in 103.2a–e in order, as applicable.

If any players are using sideboards (see rule 100.4) or cards being represented by substitute cards (see rule 713), those cards are set aside. After this happens, each player’s deck is considered their starting deck.

If any players wish to reveal a card with a companion ability that they own from outside the game, they may do so. A player may reveal no more than one card this way, and they may do so only if their deck fulfills the condition of that card’s companion ability. The revealed card remains outside the game. (See rule 702.139, “Companion.”)

In a Commander game, each player puts their commander from their deck face up into the command zone. See rule 903.6.

In a constructed game, each player playing with sticker sheets reveals all of their sticker sheets and chooses three of them at random. In a limited game, each player chooses up to three sticker sheets from among those in the sealed product they opened and reveals them. In either case, that player has access to only the stickers on the chosen sheets during the game, and those sticker sheets remain revealed. (See rule 123, “Stickers.”)

In a Conspiracy Draft game, each player puts any number of conspiracy cards from their sideboard into the command zone. See rule 905.4.

After the starting player has been determined and any additional steps performed, each player shuffles their deck so that the cards are in a random order. Each player may then shuffle or cut their opponents’ decks. The players’ decks become their libraries.

In a game using one or more supplementary decks of nontraditional cards (see rule 100.2d), each supplementary deck’s owner shuffles it so the cards are in a random order. Each player may then shuffle or cut their opponents’ supplementary decks.

Each player begins the game with a starting life total of 20. Some variant games have different starting life totals.

In a Two-Headed Giant game, each team’s starting life total is 30.

In a Vanguard game, each player’s starting life total is 20 plus or minus the life modifier of their vanguard card.

In a Commander game, each player’s starting life total is 40.

In a two-player Brawl game, each player’s starting life total is 25. In a multiplayer Brawl game, each player’s starting life total is 30.

In an Archenemy game, the archenemy’s starting life total is 40.

Each player draws a number of cards equal to their starting hand size, which is normally seven. (Some effects can modify a player’s starting hand size.) A player who is dissatisfied with their initial hand may take a mulligan. First, the starting player declares whether they will take a mulligan. Then each other player in turn order does the same. Once each player has made a declaration, all players who decided to take mulligans do so at the same time. To take a mulligan, a player shuffles the cards in their hand back into their library, draws a new hand of cards equal to their starting hand size, then puts a number of those cards equal to the number of times that player has taken a mulligan on the bottom of their library in any order. Once a player chooses not to take a mulligan, the remaining cards become that player’s opening hand, and that player may not take any further mulligans. This process is then repeated until no player takes a mulligan. A player can take mulligans until their opening hand would be zero cards, after which they may not take further mulligans.

In a Vanguard game, each player’s starting hand size is seven plus or minus the hand modifier of their vanguard card.

If an effect allows a player to perform an action “any time [that player] could mulligan,” the player may perform that action at a time they would declare whether they will take a mulligan. This need not be in the first round of mulligans. Other players may have already made their mulligan declarations by the time the player has the option to perform this action. If the player performs the action, they then declare whether they will take a mulligan.

In a multiplayer game and in any Brawl game, the first mulligan a player takes doesn’t count toward the number of cards that player will put on the bottom of their library or the number of mulligans that player may take. Subsequent mulligans are counted toward these numbers as normal.

In a multiplayer game using the shared team turns option, first each player on the starting team declares whether that player will take a mulligan, then the players on each other team in turn order do the same. Teammates may consult while making their decisions. Then all mulligans are taken at the same time. A player may take a mulligan even after a teammate has decided to keep their opening hand.

Some cards allow a player to take actions with them from their opening hand. Once the mulligan process (see rule 103.5) is complete, the starting player may take any such actions in any order. Then each other player in turn order may do the same.

If a card allows a player to begin the game with that card on the battlefield, the player taking this action puts that card onto the battlefield.

If a card allows a player to reveal it from their opening hand, the player taking this action does so. The card remains revealed until the first turn begins. Each card may be revealed this way only once.

In a multiplayer game using the shared team turns option, first each player on the starting team, in whatever order that team likes, may take such actions. Teammates may consult while making their decisions. Then each player on each other team in turn order does the same.

In a Planechase game, the starting player moves the top card of their planar deck off that planar deck and turns it face up. If it’s a phenomenon card, the player puts that card on the bottom of their planar deck and repeats this process until a plane card is turned face up. The face-up plane card becomes the starting plane. (See rule 901, “Planechase.”)

The starting player takes their first turn.

In a two-player game, the player who plays first skips the draw step (see rule 504, “Draw Step”) of their first turn.

In a Two-Headed Giant game, the team who plays first skips the draw step of their first turn.

In all other multiplayer games, no player skips the draw step of their first turn.

In constructed play, a player who chooses to play with stickers must start the game with at least ten sticker sheets selected before play begins, and each of their sticker sheets must be unique. There is no maximum number of sticker sheets a player may start the game with. Each player playing with sticker sheets reveals all of their sticker sheets and chooses three of them at random. See rule 103, “Starting the Game.”

In limited play, each player chooses up to three sticker sheets from among those in the sealed products they opened and reveals them. See rule 103, “Starting the Game.”

Each vanguard card has a hand modifier printed in its lower left corner. This is a number preceded by a plus sign, a number preceded by a minus sign, or a zero. This modifier is applied as the starting hand size and the maximum hand size of the vanguard card’s owner are determined. See rule 103.5.

Each vanguard card has a life modifier printed in its lower right corner. This is a number preceded by a plus sign, a number preceded by a minus sign, or a zero. This modifier is applied as the starting life total of the vanguard card’s owner is determined. See rule 103.4.

Each vanguard card has a hand modifier printed in its lower left corner. This is a number preceded by a plus sign, a number preceded by a minus sign, or a zero. This modifier is applied to the starting hand size and maximum hand size of the vanguard card’s owner (normally seven). The resulting number is both how many cards that player draws at the beginning of the game and their maximum hand size. See rule 103.5.

Each vanguard card has a life modifier printed in its lower right corner. This is a number preceded by a plus sign, a number preceded by a minus sign, or a zero. This modifier is applied as the starting life total of the vanguard card’s owner (normally 20) to is determined. See rule 103.4.

The hand is where a player holds cards that have been drawn. Cards can be put into a player’s hand by other effects as well. At the beginning of the game, each player draws a number of cards equal to that player’s starting hand size, normally seven. (See rule 103, “Starting the Game.”)

Bestow

Companion is a keyword ability that functions outside the game. It’s written as “Companion—[Condition].” Before the game begins, you may reveal one card you own from outside the game with a companion ability whose condition is fulfilled by your starting deck. (See rule 103.2b.) Once during the game, any time you have priority and the stack is empty, but only during a main phase of your turn, you may pay {3} and put that card into your hand. This is a special action that doesn’t use the stack (see rule 116.2g). This is a change from previous rules.

If a substitute card is used in a deck, the card it represents is set aside prior to the beginning of the game (see rule 103.2a) and must remain available throughout the game. A substitute card can’t be included in a deck unless it is representing a double-faced card or a meld card.

Attraction cards do not begin the game in a player’s deck and do not count toward maximum or minimum deck sizes. Rather, a player who chooses to play with Attraction cards begins the game with a supplementary Attraction deck that exists in the command zone. Each Attraction deck is shuffled before the game begins (see rule 103.3a).

One card (Karn Liberated) restarts the game. A game that is restarted immediately ends. No players in that game win, lose, or draw that game. All players in that game when it ended then start a new game following the procedures set forth in rule 103, “Starting the Game,” with the following exception:

As the subgame starts, an entirely new set of game zones is created. Each player takes all the cards in their main-game library, moves them to their 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 726.2a–c. Randomly determine which player goes first. The subgame proceeds like a normal game, following all other rules in rule 103, “Starting the Game.”

In a multiplayer game other than a Two-Headed Giant game, the starting player doesn’t skip the draw step of their first turn. In a Two-Headed Giant game, the team who plays first skips the draw step of their first turn. See rule 103.8.

The methods described in rule 103.1 are used to determine which team will take the first turn. The team determined this way is the starting team.

The process for handling mulligans is altered accordingly. First, each player on the starting team, in whatever order that team likes, declares whether that player will take a mulligan. Then the players on each other team in turn order do the same. Teammates may consult while making their decisions. Then all mulligans are taken at the same time. Teammates may consult while choosing which cards, if any, to put on the bottom of their library. A player may take a mulligan even after a teammate has decided to keep their opening hand. See rule 103.5.

Once all players have kept their opening hands and used the abilities of cards that allow them to take an action with those cards from their opening hands, the starting player moves the top card of their planar deck off that planar deck and turns it face up. If it’s a phenomenon card, the player puts that card on the bottom of their planar deck and repeats this process until a plane card is turned face up. (See rule 103.7.) No abilities of any card turned face up this way trigger during this process. The face-up plane card becomes the starting plane.

If a player takes a mulligan in a Vanguard game, just like in a normal game, that player shuffles their hand back into their library, then draws a new hand equal to their starting hand size. (In a multiplayer game, a player’s first mulligan is for the same number of cards as they had before.) See rule 103.5.

If a commander has a static ability that causes a player to choose its color before the game begins, that choice applies during deck construction and throughout the game, even as the commander changes zones. That choice affects the commander’s color identity. The player reveals that choice as they put their commander into the command zone before the game begins. See rules 103.2c and 607.2p.
