Ninetales. The Fox Pokemon. It is easily OU because of its ability, Drought. You may re-consider it:
Ninetales @ Leftovers:
EV: 252 HP / 252 Spe / 4 sp.ATK
- Will - O -Wisp
- Sunny Day
- Fire Blast / Flamethrower
Will - O - Wisp will let you deal with the physical attacking guys that aren't Guts Pokemon. SolarBeam, you may use this attack whenever needed so you are covering the weakness of Grass, Water and Rock Pokemon, which are all strong on Ninetales. You will use Sunny Day to win the weather war, and to make the opponent switch for Politoed or Tyranitar the will re-set up their weather so you can burn them with Will - O - Wisp, thus harnessing the Potential of Tyranitar and doing damage outside of battle, because of the little investment that this Ninetales will use in Sp.ATK. Finally, Fire Blast / Flamethrower is the offensive attack of Ninetales, the former using power, while the latter, more recommended, uses PP and accuracy in its advantage, while 135 STAB is not bad.
Actually, Infernape is OU for being a strong sweeper. Yours is perfect, although I would add Earthquake over Thunder Punch just for Power. Seriously, this one is nice.
This one fits in almost any team, while in this team, you may re-consider synergism and add the not-so-much known Rotom-Wash in Sun. Why ? Because its typing Synergize so much with your team. Try out:
Rotom-Wash @ Choice Scarf:
EV: 252 HP / 252 sp.DEF / 4 sp.ATK
- Hydro Pump
- Volt Switch
- Substitute / Will - O -Wisp
Hydro Pump is its only worthwhile STAB move, with a 180 honorable basepower. It may help if the Weather War was lost, so it's not halved. Volt Switch is a tactical move, that will help scouting and at least may deal damage. With it, if you withdrew Ninetales, you can bring it back to set up à nouveau the Weather in your advantage. Substitute may hide your Rotom so that you may use it as a wall, while Will - O - Wisp will do the same job as Ninetales's. Trick will make every wall surrender facing your awesomness.
Let's be strategic, 'K ? You will remove that thing from your team, it doesn't help. You will need a spinner, as most competitive teams prepare SR against Sun team -Especially Ninetales-.
I will add the spinner later on.
Let's say ... The awesomeness ... Ferrothorn !!
Ferrothorn @ Rocky Helmet:
Trait: Iron Barbs
EV: 252 HP / 248 sp.DEF / 8 DEF
- Stealth Rock
- Leech Seed
- Power Whip
Man, Spikes and Stealth Rock's use are for both evident: Hazards ! Whenever the opponent will feel free to switch, they'll take damage. Badass, uh ? Leech seed will heal and drain and its use is obvious, while finally, Power Whip is a reliable and powerful attack.
OK, Heatran is definitively a strong Pokemon. And it will stay on your team.
Heatran @ Focus Sash:
Trait: Flash Fire
EV: 252 Spe / 252 sp.ATK / 4 HP
- Magma Storm / Flamethrower
- Earth Power
- Flash Cannon
- Dragon Pulse
Ah, The fire move. Will it be Magma Storm or Flamethrower? I may vote up Magma Storm. It has the ability of preventing your opponent switching, inflicts massive damage and has an extend later after it occurs. Earth Power can counter other Heatrans, Terrakion and so on threats. Flash Cannon is a STAB move, and finally, you can consider Dragon Pulse so Lati-Twins, Garchomp, Salamence, Hydreigon and Dragonite are no longer problems.
U jelly ? 'cuz Reuniclus simply doesn't work in Sun Teams. It hasn't got anything to do in. Say, don't I mentioned a Spinner earlier ? We will consider "un éléphant rouge" like ...
Donphan @ Choice Band:
EV: 252 HP / 252 ATK / 4 DEF
- Rapid Spin
- Ice Shard
- Body Slam / Poison Jab / Stone Edge
Rapid Spin is to be the spinner of the team. Once hazards are gone, switch. Ice Shard is a priority and can massively hit Dragons. Surprised that it learns it. Body Slam can be used, but won't act most of the time except if the foe is really slower than Donphan. Poison Jab is also usable, has the same power and is more likely to act and leave a Poisoned Pokemon. Stone Edge is a nice move, you can consider it as a coverage. Finally, Earthquake is obviously made to destroy.
Hope I helped !
