Flamethrower, Solar Beam, Drought, Energy Ball, Shadow Ball, Substitute and Will o Wisp are all useful moves for Ninetales. You get coverage in one move and then 2 more slots for ghost coverage or weather if you choose to go Solar Beam. Even Calm Mind+Sub (Substitute) is good for a little setup. Ninetales learns all of these moves through TM.
With items, you don't have much variety. Life Orb is a common one, and so is Leftovers. You could use a Choiced set, but that would mean having weaker coverage and less move choices, so I wouldn't recommend that.
EVs: 252 Sp. A / 252 Spd / 4 Sp. D
- Energy Ball
- Calm Mind
Flamethrower is obvious STAB boosted by Calm Mind behind a Sub, with Leftovers to recover your lost HP. This way, you can at least get off one Calm Mind and then sweep with Flamethrower. Energy Ball over Solar Beam because Sub+Calm Mind is more important, and anyways, Energy Ball will be boosted by Calm Mind.
Hope I helped!
