This might not be correct, but I believe it can only be used as the alignment it was played as. For example, if you play it into your territory from a white hero, you can only use it against evil enhancements, and vice versa. Because it's placed in territory, it only matters what characters you had when you played it, not when you use it.
You have to chose who you play it in when you put it down, so having both down doesn't let it target any/every enhancement. You still have to pick if it is white or brown when you play it.
