Means basically every Pokemon that doesn't get STAB on either type can hit it super-effectively, but has to waste a moveslot on a move that is basically useless outside of beating fairies. --- "I am champion of Bellator.

That would make almost everything useless. Also, Fairy/Steel for the win, I guess. Nothing's gonna hurt this much at all, and Steel takes away the Normal Weakness while turning the Poison Weakness into an immunity.
