Rule 113.10 · Abilities
Effects can add or remove abilities of objects. An effect that adds an ability will state that the object “gains” or “has” that ability, or similar. An effect that removes an ability will state that the object “loses” that ability.
Subrules
An effect that adds an activated ability may include activation instructions for that ability. These instructions become part of the ability that’s added to the object.
Effects that remove an ability remove all instances of it.
