Q: If I have a Goal which requires Creepers, and I’m playing with a deck that has duplicate Creepers do extras of one of the Creepers required prevent my win?

…for example, for the Goal Enemy Alliance that requires Romulans and Klingons, if I have both the TNG and TOS versions of the Romulans Creeper, does the second Romulans count as an extra Creeper which prevents my win, as mentioned in this FAQ? Or is it just more of what I need to win?

A: Since the Goal specifically mentions Romulans without specifying one of the other, they’re effectively identical, and both count towards the Goal and not against it, and it doesn’t matter that you have a superfluous one. It’s more like what’s described in this FAQ.
