Rather than a mirror, I suggest a sort of weapon. When Link land the killing blow on a foe with this weapon, he assumes the form and identity of the defeated enemy, complete with all of that foe's strengths and weaknesses. And why end it there? Additionally, you could add the ability to converse with enemies of the same class (where appropriate), giving opportunity for some interesting dialogue and possibly even some zany side-quests. It would certainly be useful in a situation that demands stealth, for certain.
