This is probably my best team, but it has a problem and I would like you gave me the solution!
Building Phase:
The team is very synergistic and I could to start from every Pokemon and get to the same team. I using the method called “Counter Systerm” because it is easier to explain!
Rain Team = Politoed!
It is weak to Electro and Grass covered by Ferrothorn.
Ferrothorn is weak to Fire and Fighting covered by Tentacruel.
Tentacruel is weak to Psycho (Ferrothorn), Electro (Ferrothorn) and Earth covered by Thundurus-T.
Thundurus-T is weak to the Rock (Ferrothorn) and Ice (Tentacruel).
Now I choose Scizor to create the Volturn Chain with Thundurus-T, the weakness to Fire is covered by Tentacruel.
The last Pokemon is a Physical Sweeper, Gyarados. It is weak Electro and Rock covered by Ferrothorn.
Politoed @ Choice Specs
Trait: Drizzle
EVs: 252 HP / 252 SAtk / 4 Spd
Modest Nature
- Hydro Pump
- Ice Beam
- Focus Blast
- Hidden Power [Grass]
Weather, Specser, Special Sweepers.
Hydro Pump STAB.
Ice Beam counters Dragon, Landorus(-T), Thundurus-T, Tornadus, Grass ecc…
Focus Blast counters Tyranitar, Magnezone, Steel, Abomasnow ecc…
HP Grass counters Gastrodon, Jellicent, Starmie and other Water.
I chose Specser Politoed because in front of Politoed many switch and Hydro Pump is always a good choice seen the damage it does, then it is better to Scarfer Politoed because I do not care the speed in these situations. I do not like Defensive Politoed because the best defensive Pokemon Water is Tentacruel and it makes no sense to have 2 Pokemon with the same function.
Tentacruel @ Black Sludge
Trait: Rain Dish
EVs: 252 HP / 240 Def / 16 Spd
Timid Nature
- Toxic
- Rapid Spin
- Scald
- Substitute
Annoyer, Spinner, Supporter, Entry Hazard, Tanks, Wall.
Scald STAB. Rapid Spin staple.
Substitute is very durable and allows me to take a turn instead of wasting Toxic on a Steel. It also gives me the chance to do 1 or 2 Scald before switch.
Toxic is better than Toxic Spikes in this set.
Tentacruel is the best defensive Pokemon with Rapid Spin in a Rain Team.
Ferrothorn @ Leftovers
Trait: Iron Barbs
EVs: 252 HP / 88 Def / 168 SDef
Impish Nature
- Stealth Rock
- Leech Seed
- Power Whip
- Protect
Spiker, Supporter, Entry Hazard, Tanks, Wall
Power Whip STAB.
Stealth Rock and Leech Seed staple.
Protect because with Leech Seed and Leftovers I can recover HP and extend the longevity of Ferrothorn.
Ferrothorn is the best Pokemon Steel capable of stalling.
Thundurus-Therian (M) @ Choice Scarf
Trait: Volt Absorb
EVs: 4 Def / 252 SAtk / 252 Spd
Timid Nature
- Volt Switch
- Thunder
- Hidden Power [Ice]
- Focus Blast
Scarfer Special Sweepers, Revenge-killing
Thunder STAB.
Volt Switch STAB and Volturn Chain, too Broken!
Hidden Power [Ice] counters Dragon, Landorus(-T), Earth ecc…
Focus Blast counters Tyranitar, Magnezone, Steel, Abomasnow ecc…
Thundurus-T becomes with Scraf one of the fastest Pokemon in OU so as to exploit Volt Switch e Thunder ends the opposing team once they no longer Pokemon resistant to Electro.
Scizor @ Choice Scarf
Trait: Technician
EVs: 252 Atk / 4 SDef / 252 Spd
Jolly Nature
- U-turn
- Bullet Punch
- Superpower
- Pursuit
Lead, Scarfer Sweepers, Revenge-killing
U-turn STAB and Volturn Chain, too broken!
Bullet Punch STAB.
Superpower counters Tyranitar, Heatran, Magnezone, Steel, Abomasnow, Chansey and Blissey ecc…
Pursuit counter Psychic, Volcarona after Stealth Rock, really good after Draco Meteor.
Scizor complete Volturn Chain with U-Turn STAB. Scizor is a Lead that recalls the Fire moves so I can to switch in Politoed. Scizor requires you to change the Ninjask and Dragons as lead.
I prefer Scarf Scizor because my goal is to attack first with U-turn. CBander Scizor is more focused on Bullet Punch and do not care. Scizor is too slow in the current meta, it would not resist to more than two attacks.
Gyarados @ Leftovers
Trait: Moxie
Shiny: Yes
EVs: 56 HP / 248 Atk / 204 Spd
Adamant Nature
- Waterfall
- Substitute
- Dragon Dance
- Bounce
Annoyer Dancer, Sweepers, Entry Hazard
Waterfall STAB, too broken under Rain!
Bounce STAB.
Dragon Dance makes Gyarados one of the fastest Pokemon in OU. After 2 Dragon Dances won.
Substitute protects from WoW and Toxic. It also protects the moves "unpredictable" or unusual.
Gyarados uses Rain with a physical STAB. In more enhanced once it becomes a winning conditions. Log on Earth moves that target Tentacruel and create substitute the resulting Switch.
Now I will talk about the problem.
The problem is called Magnezone!
With HP Fire traps and kills Ferrothorn and Scizor. Politoed, Tentacruel and Gyarados succumb to an attack Electric.
Obviously I will change in Thundurus-T and my opponent will prepare HP Fire takes away 75% of HP Thundurus-T (with Stealth Rock is 1OHKO) and under Sun 1OHKO Thundurus-T and HP Ice 1OHKO Thundurus-T.
My only chance is revenge-killing with Focus Blast, are very unlucky and always fails, ALWAYS!
Do you have a better solution?
The only solution I can think of is to put another Pokemon with U-turn instead of Scizor that is not weak to Water (I will not use Pokemon that can be weakened by Rain).
Building Phase:
The team is very synergistic and I could to start from every Pokemon and get to the same team. I using the method called “Counter Systerm” because it is easier to explain!
