Flareon

Seeing as u already have so many fire types for attacking, I'll suggest u not power the new Flareon up. Only if u have lots of stardust to spare and a heck lot of Eevee candys then power that Flareon up

I plan on powering up a Flareon with that moveset in the near future because it can be used on both offense and defense. I plan to use it for defense, but ft gives a squishy pokemon better dodging ability. But that is me. If I were in your position, I would only do it if you are looking for a defender, because you clearly have enough attackers.

FS/Flame thower flareon performs fairly well in attack in fact, and I always keep him in mind after my first attacker died as its charge attack is a 2-bar.

Flareon's best defensive moveset, if you care about that. Still a good offensive movest, just not the best. Fire Spin spits out a lot of extra damage compared to Ember.
