Self's identifier says that its identifiers and abilities copy that of a selected opponent's Hero in play.
...what if there aren't any?
And when there is, is it still considered generic regardless?
Furthermore, seeing as its abilities matching those of an opponent's Hero in play is actually the special ability of Self, does that mean that selecting a Hero to copy does not happen until Self enters battle? If this is the case, does it not remain a non-human non-demon generic genderless Evil Character of every brigade with no abilities until it enters battle?
