Core Set 2020 Commander 2019
106.8.
If an effect would add mana represented by a hybrid mana symbol to a player’s mana pool, that player chooses one half of that symbol. If a colored half is chosen, one mana of that color is added to that player’s mana pool. If a colorless half is chosen, an amount of colorless mana represented by that half’s number is added to that player’s mana pool.
106.8.
If an effect would add mana represented by a hybrid mana symbol to a player’s mana pool, that player chooses one half of that symbol. If a colored half is chosen, one mana of that color is added to that player’s mana pool. If a generic half is chosen, an amount of colorless mana represented by that half’s number is added to that player’s mana pool.
107.3d
If a cost associated with a special action, such as a suspend cost or a morph cost, has an {X} or an X in it, the value of X is chosen by the player taking the special action as they pay that cost.
107.3d
If a cost associated with a special action, such as a suspend cost or a morph cost, has an {X} or an X in it, the value of X is chosen by the player taking the special action immediately before they pay that cost.
110.2b
If an effect causes a player to gain control of another player’s permanent spell, the first player controls the permanent that spell becomes, but the permanent’s controller by default is the player who put that spell onto the stack. (This distinction is relevant in multiplayer games; see rule 800.4c.)
118.7e
If a cost is reduced by an amount of mana represented by a hybrid mana symbol, the player paying that cost chooses one half of that symbol at the time the cost reduction is applied (see rule 601.2f). If a colored half is chosen, the cost is reduced by one mana of that color. If a colorless half is chosen, the cost is reduced by an amount of generic mana equal to that half’s number.
118.7e
If a cost is reduced by an amount of mana represented by a hybrid mana symbol, the player paying that cost chooses one half of that symbol at the time the cost reduction is applied (see rule 601.2f). If a colored half is chosen, the cost is reduced by one mana of that color. If a generic half is chosen, the cost is reduced by an amount of generic mana equal to that half’s number.
118.13.
Some costs contain mana symbols that can be paid in multiple ways. These include hybrid mana symbols and Phyrexian mana symbols.
118.13a
If the mana cost of a spell or the activation cost of an activated ability contains a mana symbol that can be paid in multiple ways, the choice of how to pay for that symbol is made as its controller proposes that spell or ability (see rule 601.2b).
118.13b
If a cost paid during the resolution of a spell or ability contains a mana symbol that can be paid in multiple ways, the player paying that cost chooses how to pay for that symbol immediately before they pay that cost.
118.13c
If the cost associated with a special action contains a mana symbol that can be paid in multiple ways, the player taking the special action chooses how to pay for that symbol immediately before they pay that cost.

303.4k
If an effect allows an Aura that’s being turned face up to become attached to an object or player, the Aura’s controller considers the characteristics of that Aura as it would exist if it were face up to determine what it may be attached to, and they must choose a legal object or player according to the Aura’s enchant ability and any other applicable effects.
400.7a
Effects from spells, activated abilities, and triggered abilities that change the characteristics of a permanent spell on the stack continue to apply to the permanent that spell becomes.
400.7a
Effects from spells, activated abilities, and triggered abilities that change the characteristics or controller of a permanent spell on the stack continue to apply to the permanent that spell becomes.
508.4.
If a creature is put onto the battlefield attacking, its controller chooses which defending player or which planeswalker a defending player controls it’s attacking as it enters the battlefield (unless the effect that put it onto the battlefield specifies what it’s attacking). Such creatures are “attacking” but, for the purposes of trigger events and effects, they never “attacked.”
508.4.
If a creature is put onto the battlefield attacking, its controller chooses which defending player or which planeswalker a defending player controls it’s attacking as it enters the battlefield (unless the effect that put it onto the battlefield specifies what it’s attacking). Similarly, if an effect states that a creature is attacking, its controller chooses which defending player or which planeswalker a defending player controls it’s attacking it becomes attacking (unless the effect has already specified). Such creatures are “attacking” but, for the purposes of trigger events and effects, they never “attacked.”
508.4b
If the effect that states a creature is attacking specifies it’s attacking a certain player, and that player is no longer in the game when the effect resolves, the creature doesn’t become an attacking creature. The same is true if the effect specifies a creature is attacking a planeswalker and that planeswalker is no longer on the battlefield or is no longer a planeswalker when the effect resolves.
508.4b
A creature that’s put onto the battlefield attacking isn’t affected by requirements or restrictions that apply to the declaration of attackers.
508.4c
A creature that’s put onto the battlefield attacking or that is stated to be attacking isn’t affected by requirements or restrictions that apply to the declaration of attackers.
701.37b
A static ability may state that a creature “is goaded.” That creature attacks each combat if able and attacks a player other than the controller of the permanent with that static ability if able.
701.37c
Once a player has goaded a creature, the same player goading it again has no effect. It doesn’t create additional combat requirements.
702.1c
An effect may state that “the same is true for” a list of keyword abilities. If one of those keyword abilities has variants or variables and the effect grants that keyword to one or more objects and/or players, it grants each appropriate variant and variable of that keyword.
702.1d
An effect may refer to an object “with [keyword ability]” or “that has [keyword ability].” This means the same thing as an object “with a [keyword ability] ability” or an object “that has a [keyword ability] ability.”
702.16i
“Protection from each [set of characteristics, qualities, or players]” is shorthand for “protection from [A],” “protection from [B],” and so on for each characteristic, quality, or player in the set. It behaves as multiple separate protection abilities.
706.9f
Some replacement effects that generate copy effects are linked to triggered abilities written in the same paragraph. (See rule 603.11.) The triggered ability will only trigger if the resulting object after applying all continuous effects has that ability.
716.1b
Exile every object on the stack, including the object that’s resolving. Remove all creatures and planeswalkers from combat. All objects not on the battlefield or in the command zone that aren’t represented by cards will cease to exist the next time state–based actions are checked (see rule 704, “State–Based Actions”).
716.1b
Exile every object on the stack, including the object that’s resolving. All objects not on the battlefield or in the command zone that aren’t represented by cards will cease to exist the next time state–based actions are checked (see rule 704, “State–Based Actions”).
716.1d
The current phase and/or step ends. The game skips straight to the cleanup step; skip any phases or steps between this phase or step and the cleanup step. If an effect ends the turn during the cleanup step, a new cleanup step begins.
716.1d
The current phase and/or step ends. If this happens during combat, remove all creatures and planeswalkers from combat. The game skips straight to the cleanup step; skip any phases or steps between this phase or step and the cleanup step. If an effect ends the turn during the cleanup step, a new cleanup step begins.
716.2.
One card (Mandate of Peace) ends the combat phase. When an effect ends the combat phase, follow these steps in order, as they differ from the normal process for resolving spells and abilities (see rule 608, “Resolving Spells and Abilities”).
716.2a
If there are any triggered abilities that triggered before this process began but haven’t been put onto the stack yet, those abilities cease to exist. They won’t be put onto the stack. This rule does not apply to abilities that trigger during this process (see rule 716.2f).
716.2b
Exile every object on the stack, including the object that’s resolving. All objects not on the battlefield or in the command zone that aren’t represented by cards will cease to exist the next time state–based actions are checked (see rule 704, “State–Based Actions”).
716.2c
Check state–based actions. No player gets priority, and no triggered abilities are put onto the stack.
716.2d
The current combat phase ends. Remove all creatures and planeswalkers from combat. Effects that last “until end of combat” expire. The game skips straight to the next phase, usually the postcombat main phase; skip any steps between this step and that phase.
716.2e
Even though the combat phase ends, “at end of combat” triggered abilities don’t trigger because the end of combat step is skipped.
716.2f
No player gets priority during this process, so triggered abilities are not put onto the stack. If any triggered abilities have triggered since this process began, those abilities are put onto the stack during the following phase, then the active player gets priority and players can cast spells and activate abilities.
716.2g
If an effect attempts to end the combat phase at any time that’s not a combat phase, nothing happens.
800.4c
If an effect that gives a player still in the game control of an object ends, there is no other effect giving control of that object to another player in the game, and the object entered the battlefield under the control of a player who has left the game, the object is exiled. This is not a state–based action. It happens as soon as the control–changing effect ends.
800.4c
If an effect that gives a player still in the game control of an object ends, there is no other effect giving control of that object to another player in the game, and the player who controlled that object by default has left the game, the object is exiled. This is not a state–based action. It happens as soon as the control–changing effect ends.
800.4h
If an effect requires information about a specific player, the effect uses the current information about that player if they are still in the game; otherwise, the effect uses the last known information about that player before they left the game.
800.4h
If an effect requires information about a specific player, the effect uses the current information about that player if they are still in the game; otherwise, the effect uses the last known information about that player before they left the game. If an effect requires information from the game about actions players have taken, the effect can find actions that were taken by a player who has left the game.
800.5.
Unless a chosen variant or option prescribes otherwise, seating order is determined by any mutually agreeable method. For example, players could agree to remain where they were before the game began, roll dice to determine seating order, and so on.
