You can kill him without using a trump card. A trump card isn't "something that can kill him", it's "the greatest capability" of a being, though this is an oversimplification.There are also ways to beat Fragarach, even if a trump card is used. Blah, I said I wouldn't post anymore. BB already explained this. Etc.

Actually, this hasn't been properly explained that I have seen. Stein's trump card is his intelligence, that's his greatest capability, but that's not a power at all. It's simply what he relies on to win battles. Does that mean it'll rewind time to before he began thinking, and kill Stein before he's born? because that would just be plain silly.
