Answer 1

Gen VIII
Ninetales@ Charcoal
Nature: Modest
Evs: 252 Sp.A / 4 Spd / 126 Sp.D / 126 Def
Ability: Drought
- Nasty Plot
- Flamethrower / Fire Blast / Fire Spin
- Energy Ball / Solar Beam
- Sunny Day / Hex

Drought sets up the sun so Ninetales gains a power boost as soon as it is sent out. Nasty Plot further boosts Ninetales' special attack, therefore boosting the power of its attacks. The STAB move, you can decide from Flamethrower, Fire Blast and Fire Spin (personally I would use Fire Spin). Your coverage move depends on whether you use Sunny Day or Hex. If you choose Hex, use Energy Ball. If you choose Sunny Day you get a boost in your Fire moves and Solar Beam executes in 1 turn. Sunny Day and Energy Ball can also be used.

Answer 2

Ninetales @ White Herb (Gen 9 RU)
EVs: 252 Speed/252 Special Attack/4 Special Defense
Ability: Flash Fire
Modest Nature

-Heat Wave
-Overheat
-Psychic
-Energy Ball

You can get a boosted Overheat or Heat Wave if you switch into a Fire move thanks to Flash Fire. White Herb resets your stats when they are dropped, allowing you to use multiple Overheats. Heat Wave is STAB with a chance for a burn. Psychic and Energy Ball are for coverage. I hope you enjoy this set!
