2 rulings from Wizards of the Coast
- 24 January 2013Homing Lightning has only one target. Other creatures with that name are not targeted. For example, a creature with hexproof will be dealt damage if it has the same name as the target creature.
- 10 June 2022Unless a token is a copy of another permanent or was explicitly given a name by the effect that created it, its name is the subtypes it was given when it was created plus the word "Token." For example, if an effect creates a 1/1 Soldier creature token, that token is named "Soldier Token."
