If you really wanna use Ninetales, Drought can help Fire Blast on Salamence actually pack a real punch; and flash fire can provide an excellent switch in if you use Mega Mawile and sense a fire attack coming.
Other than thaaaaat, ahhhhh - Empoleon can scare fairies, tank ice, and provide fair coverage for the pokemon you have already down. Stacks a few steel types; but you do have salamence to take ground and fighting attacks, and Ninetales to take fire again .
Ninetales is used for one reason only: Drought. Chandelure makes a better Flash Fire abuser because of its better raw power compared to Ninetales.
Outside of the odd Defiant set (which Bisharp does loads better, thanks to better Attack), I don't see much use for Empoleon in doubles. Mega Mawile tanks Ice attacks fine already, if you do go for that. Another alternative is Metagross, which has been used in doubles matches frequently in the past. Excadrill is also an alternative because its spread Earthquake doesn't damage Salamence, though it causes problems for Wash Rotom thanks to Mold Breaker ignoring Levitate. Other Steel alternatives include Bisharp, Escavalier, Scizor, Klefki and Heatran:
