My comment about U-turn / Air Slash is for Specs only. Air Slash seems counter intuitive until you realize how easy it is to beat down Sun Teams with it. Air slash comfortably 3HKOs SpDef Ninetales, and 2HKOs offensive ones. Air Slash gives you something to spam if leading with Politoed isn't permitted. U-turn I've never found useful at all on the Specs set.. Jirachi is the only thing you would use it against because nothing likes just getting beat down by Hurricane.
