- 106.1 Mana is the primary resource in the game. Players spend mana to pay costs, usually when casting spells and activating abilities.
106.1a There are five colors of mana: white, blue, black, red, and green.
106.1b There are six types of mana: white, blue, black, red, green, and colorless.
106.2 Mana is represented by mana symbols (see rule 107.4). Mana symbols also represent mana costs (see rule 202).
106.3 Mana is produced by the effects of mana abilities (see rule 605). It may also be produced by the effects of spells, as well as by the effects of abilities that aren’t mana abilities.
106.4 When an effect produces mana, that mana goes into a player’s mana pool. From there, it can be used to pay costs immediately, or it can stay in the player’s mana pool. Each player’s mana pool empties at the end of each step and phase.
106.4a If a player passes priority (see rule 116) while there is mana in his or her mana pool, that player announces what mana is there. If any mana remains in a player’s mana pool after he or she spends mana to pay a cost, that player announces what mana is still there.
106.5 If an ability would produce one or more mana of an undefined type, it produces no mana instead. Example: Meteor Crater has the ability "Tap: Choose a color of a permanent you control. Add one mana of that color to your mana pool." If you control no colored permanents, activating Meteor Crater’s mana ability produces no mana.
106.6 Some spells or abilities that produce mana restrict how that mana can be spent, have an additional effect that affects the spell or ability that mana is spent on, or create a delayed triggered ability (see rule 603.7a) that triggers when that mana is spent. This doesn’t affect the mana’s type.
106.6a Some replacement effects increase the amount of mana produced by a spell or ability. In these cases, any restrictions or additional effects created by the spell or ability will apply to all mana produced. If the spell or ability creates a delayed triggered ability that triggers when the mana is spent, a separate delayed triggered ability is created for each mana produced.
106.7 Some abilities produce mana based on the type of mana another permanent or permanents "could produce." The type of mana a permanent could produce at any time includes any type of mana that an ability of that permanent would produce if the ability were to resolve at that time, taking into account any applicable replacement effects in any possible order. Ignore whether any costs of the ability could or could not be paid. If that permanent wouldn’t produce any mana under these conditions, or no type of mana can be defined this way, there’s no type of mana it could produce.
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.
- 106.9 If an effect would add mana represented by a Phyrexian mana symbol to a player’s mana pool, one mana of the color of that symbol is added to that player’s mana pool.
- 106.10 If an effect would add mana represented by a generic mana symbol to a player’s mana pool, that much colorless mana is added to that player’s mana pool.
- 106.11 To "tap a permanent for mana" is to activate a mana ability of that permanent that includes the %Tap symbol in its activation cost. See rule 605, "Mana Abilities."
- 106.11a An ability that triggers whenever a permanent "is tapped for mana" or "is tapped for mana [of a specified type]" triggers whenever such a mana ability resolves and produces mana or the specified type of mana.
- 106.12 One card (Drain Power) puts all mana from one player’s mana pool into another player’s mana pool. (Note that these may be the same player.) This empties the former player’s mana pool and causes the mana emptied this way to be put into the latter player’s mana pool. Which permanents, spells, and/or abilities produced that mana are unchanged, as are any restrictions or additional effects associated with any of that mana.
