Declaration in Stone

Unless 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."

Declaration in Stone has only one target. The other creatures with that name aren't targeted. For example, a creature with hexproof will be exiled if it has the same name as the target creature.

Clue is an artifact type. Even though it appears on some cards with other permanent types, it's never a creature type, a land type, or anything but an artifact type.
