Actually in Gen 4 Ubers Choice Scarf Gengar used to run Icy Wind AND Hidden Power Fire to make sure he can check/revenge kill both steels and dragons and actually in Gen 5 OU it may work as well taking into account how many of them are x4 weak to Fire and Ice. Although not sure if Icy Wind is strong enough to KO Dragonite (against Salamence it's strong enough). IMO I would mention a possibility of using Icy Wind and HP Fire in OO at least.
