Rule 136.2.d

Effect Text may refer to “this” or to the name of the Attached game object that appended the Effect Text. Doing so refers to the Attached game object and not the Top-Most Card, even if the Top-Most Card shares a name with the Attached game object. Example: Guardian Angel’s effect text reads “If I would die, kill Guardian Angel instead. Heal me, exhaust me, and recall me.” Example: Brutalizer’s effect text reads “If this was attached to me this turn, I have an additional +2 [M].” The “this” in the effect text refers to the attached Brutalizer.
