113. Abilities

113.1
An ability can be one of three things:
113.10
Effects can add or remove abilities of objects
113.11
Effects can stop an object from having a specified ability
113.12
An effect that sets an object’s characteristic, or simply states a quality of that object, is different from an ability granted by an effect. When an object “gains” or “has” an ability, that ability can be removed by another effect. If an effect defines a characteristic of the object (“[permanent] is [characteristic value]”), it’s not granting an ability. (See rule 604.3.) Similarly, if an effect states a quality of that object (“[creature] can’t be blocked,” for example), it’s neither granting an ability nor setting a characteristic.
113.2
Abilities can affect the objects they’re on
113.3
There are four general categories of abilities:
113.4
Some activated abilities and some triggered abilities are mana abilities. Mana abilities follow special rules: They don’t use the stack, and, under certain circumstances, a player can activate mana abilities even if they don’t have priority. See rule 605, “Mana Abilities.”
113.5
Some activated abilities are loyalty abilities
113.6
Abilities of an instant or sorcery spell usually function only while that object is on the stack. Abilities of all other objects usually function only while that object is on the battlefield. The exceptions are as follows:
113.7
The source of an ability is the object that generated it
113.8
The controller of an activated ability on the stack is the player who activated it. The controller of a triggered ability on the stack (other than a delayed triggered ability) is the player who controlled the ability’s source when it triggered, or, if it had no controller, the player who owned the ability’s source when it triggered. To determine the controller of a delayed triggered ability, see rules 603.7d–f.
113.9
Activated and triggered abilities on the stack aren’t spells, and therefore can’t be countered by anything that counters only spells. Activated and triggered abilities on the stack can be countered by effects that specifically counter abilities. Static abilities don’t use the stack and thus can’t be countered at all.
