You, Your

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 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 played the ability. For a triggered ability, this is the controller of the object when the ability triggered, unless it's a delayed triggered ability. For a delayed triggered ability, this is the controller of the spell or ability that created it. See also Controller, Owner.
