109.2 If a spell or ability uses a description of an object that includes a card type or subtype, but doesn’t refer to a specific zone or include the word “card,” “spell,” “source,” or “scheme,” it means a permanent of that card type or subtype on the battlefield.
109.2a If a spell or ability uses a description of an object that includes the word “card” and the name of a zone, it means a card matching that description in the stated zone.
109.2c If a spell or ability uses a description of an object that includes the word “source,” it means a source matching that description—a source of an ability, of damage, or of mana—in any zone. See rules 113.7 and 609.7.
109.3 An object’s characteristics are name, mana cost, color, color indicator, card type, subtype, supertype, rules text, abilities, power, toughness, loyalty, defense, hand modifier, and life modifier. Objects can have some or all of these characteristics. Any other information about an object isn’t a characteristic. For example, characteristics don’t include whether a permanent is tapped, a spell’s target, an object’s owner or controller, what an Aura enchants, and so on.
109.4 Only objects on the stack or on the battlefield have a controller. Objects that are neither on the stack nor on the battlefield aren’t controlled by any player. See rule 108.4. There are six exceptions to this rule:
109.4b A triggered ability that has triggered but is waiting to be placed on the stack is controlled by the player who controlled its source at the time it triggered, unless it’s a delayed triggered ability. To determine the controller of a delayed triggered ability, see rules 603.7d–f. See also rule 603, “Handling Triggered Abilities.”
109.4d In a Planechase game, a face-up plane or phenomenon card is controlled by the player designated as the planar controller. This is usually the active player. See rule 901.6.
109.5 The words “you” and “your” on an object refer to the object’s controller, its would-be controller (if a player is attempting to play, cast, or activate it), or its owner (if it has no controller). For a static ability, this is the current controller of the object it’s on. For an activated ability, this is the player who activated the ability. For a triggered ability, this is the controller of the object when the ability triggered, unless it’s a delayed triggered ability. To determine the controller of a delayed triggered ability, see rules 603.7d–f.
