406 - Mana Abilities
- 406.1 - A mana ability is either (a) an activated ability that could put
mana into a player's mana pool when it resolves or (b) a triggered ability
that triggers from a mana ability and could produce additional mana. A
mana ability can generate other effects at the same time it produces mana.
[CompRules 2003/07/01]
- 406.2 - Spells that put mana into a player's mana pool aren't mana
abilities. They're played and resolved exactly like any other spells.
Triggered abilities that put mana into a player's mana pool aren't mana
abilities if they trigger from events other than activating mana
abilities. They go on the stack and resolve like any other triggered
abilities. [CompRules 2003/07/01]
- 406.3 - A mana ability remains a mana ability even if the game state doesn't
allow it to produce mana. [CompRules 2003/07/01]
Example: A permanent has an ability that reads "{Tap}: Add {G} 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.
[CompRules 2003/10/01]
- 406.4 - A mana ability can be activated or triggered. Mana abilities are
played and resolved like other abilities, but they don't go on the stack,
so they can't be countered or responded to. See Rule 411, "Playing Mana
Abilities," and Rule 408.2, "Actions That Don't Use the Stack."
[CompRules 2003/07/01]
- 406.5 - Abilities (other than mana abilities) that trigger on playing mana
abilities do use the stack. [CompRules 2003/07/01]
- 406.6 - If a mana ability would produce one or more mana of an undefined
type, it produces no mana instead. [CompRules 2003/12/01]
Example: If you control no lands, an ability that reads "{Tap}: Add to
your mana pool one mana of any type that a land you control could produce"
will not produce any mana. [CompRules 2003/12/01]
- 406.Ruling.1 - If a mana ability can't produce any mana, it's still legal to
play the ability, but no mana will be produced on resolution.
