Règles complètes de Magic: The Gathering

605.1.

Some activated abilities and some triggered abilities are mana abilities, which are subject to special rules. Only abilities that meet either of the following two sets of criteria are mana abilities, regardless of what other effects they may generate or what timing restrictions (such as «Activate this ability only any time you could cast an instant») they may have.

605.1a

An activated ability is a mana ability if it meets three 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.»)

605.1b

A triggered ability without a target that triggers from activating a mana ability and could put mana into a player‘s mana pool when it resolves is a mana ability.

605.2.

A mana ability remains a mana ability even if the game state doesn‘t allow it to produce mana. Example: A permanent has an ability that reads “: Add to your mana pool for each creature you control.” This is still a mana ability even if you control no creatures or if the permanent is already tapped.

605.3.

Activating an activated mana ability follows the rules for activating any other activated ability (see rule 602.2), with the following exceptions:

605.3a

A player may activate an activated mana ability whenever he or she has priority, whenever he or she is casting a spell or activating an ability that requires a mana payment, or whenever a rule or effect asks for a mana payment, even if it‘s in the middle of casting or resolving a spell or activating or resolving an ability.

605.3b

An activated mana ability doesn‘t go on the stack, so it can‘t be targeted, countered, or otherwise responded to. Rather, it resolves immediately after it is activated. (See rule 405.6c.)

605.4.

Triggered mana abilities follow all the rules for other triggered abilities (see rule 603, «Handling Triggered Abilities»), with the following exception:

605.4a

A triggered mana ability doesn‘t go on the stack, so it can‘t be targeted, countered, or otherwise responded to. Rather, it resolves immediately after the mana ability that triggered it, without waiting for priority. Example: An enchantment reads, “Whenever a player taps a land for mana, that player adds one mana to his or her mana pool of any type that land produced.” If a player taps lands for mana while casting a spell, the additional mana is added to the player?s mana pool immediately and can be used to pay for the spell.

605.5.

Abilities that don‘t meet the criteria specified in rules 605.1a–b and spells aren‘t mana abilities.

605.5a

An ability with a target is not a mana ability, even if it could put mana into a player‘s mana pool when it resolves. The same is true for a triggered ability that could produce mana but triggers from an event other than activating a mana ability, or a triggered ability that triggers from activating a mana ability but couldn‘t produce mana. These follow the normal rules for activated or triggered abilities, as appropriate.

605.5b

A spell can never be a mana ability, even if it could put mana into a player‘s mana pool when it resolves. It‘s cast and resolves just like any other spell. Some older cards were printed with the card type «mana source»; these cards have received errata in the Oracle card reference and are now instants.
