No name versus Same name
If a creature has no name at all, does it have the same name as all other creatures with no name, or does a creature have to have a name to have the same name as something else? (E.g. Lands do not have power and toughness at all, so we cannot ask this question of a land)
Is there a rule that speaks to this comparison?
EXAMPLE:
Norman controls two face-down morphed creatures, both Zoetic Caverns. Alan casts Bile Blight targeting one of Norman's face-down morphed creatures.
If there are no responses, does Bile Blight kill both creatures?
