First of all, I'd like to point out that I'm French and there may be spelling mistakes in my texts. I apologize if that's the case.
One Pokémon complements both Pokémon well (and Serperior is the only Grass-type Pokémon in OU 6G (Ferrothorn would add a third Steel-type Pokémon, and it's not a Monotype team).
Then Scarf Keldeo is the best Revenge-Killer in the tier.
And finally, the Tank Chomp + Spe Def Zapdos duo.
Chief Wally (Metagross-Mega) @ Metagrossite
Ability: Tough Claws
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Meteor Mash
- Zen Headbutt
- Earthquake
- Bullet Punch
This Pokémon is so powerful that it was banned in Gen 7. It has good attack, decent speed, a good ability that boosts its moves, and also a nice bulk (it has more defense than attack).
252 Atk Pure Power Medicham-Mega High Jump Kick vs. 0 HP / 0 Def Metagross-Mega: 249-294 (82.7 - 97.6%) -- guaranteed 2HKO
252+ SpA Life Orb Kyurem-Black Earth Power vs. 0 HP / 4 SpD Metagross-Mega: 244-289 (81 - 96%) -- guaranteed 2HKO
Meteor Mash and Zen Headbutt are there for STAB attacks.
Earthquake allows you to effectively hit Steel-type Pokémon, as well as Volcanion, Victini, and more.
Bullet Punch is there for priority, allowing you to better manage Mega Diancie, Weavile, or other faster threats like Mega Lopunny or Mega Alakazam.
252 Atk Tough Claws Metagross-Mega Bullet Punch vs. 0 HP / 0 Def Diancie-Mega: 340-408 (141 - 169.2%) -- guaranteed OHKO
252 Atk Tough Claws Metagross-Mega Bullet Punch vs. 0 HP / 4 Def Weavile: 260-308 (92.5 - 109.6%) -- 56.3% chance to OHKO
252 Atk Tough Claws Metagross-Mega Bullet Punch vs. 0 HP / 4 Def Lopunny-Mega: 97-115 (35.7 - 42.4%) -- guaranteed 3HKO
252 Atk Tough Claws Metagross-Mega Bullet Punch vs. 0 HP / 4 Def Alakazam-Mega: 130-154 (51.7 - 61.3%) -- guaranteed 2HKO
Melfire (Heatran) @ Leftovers
Ability: Flash Fire
EVs: 64 HP / 192 SpA / 252 Spe
Modest Nature
IVs: 0 Atk
- Magma Storm
- Earth Power
- Toxic
- Taunt
Heatran can manage a lot of threats in the tier thanks to its numerous resistances while being able to manage stalled teams thanks to the Toxic + Taunt combo with its signature move Magma Storm. Earth Power is here for the coverage.
Maximum Speed lets Heatran outspeed most defensive Pokemon, such as Zapdos and Gliscor. 64 HP EVs with Leftovers allow Heatran to take on five Seismic Tosses instead of four from Chansey, which is crucial for Heatran's stallbreaking ability. The rest of the EVs are put into Special Attack with a Modest nature to provide Heatran with as much wallbreaking power as possible.
AnneSoFruit (Serperior) @ Leftovers
Ability: Contrary
EVs: 56 HP / 200 SpA / 252 Spe
Timid Nature
IVs: 0 Atk / 30 SpA / 30 Spe
- Leaf Storm
- Hidden Power [Fire]
- Glare
- Substitute
Serperior is an excellent utility Pokémon capable of paralyzing opposing Pokémon with Glare and can weaken certain threats to allow our other Pokémon to be able to sweep.
Leaf Storm uses Contrary to boost its Special Attack (although, with its Special Attack being a bit weak (or rather knackered) and the Grass-type's mediocre coverage, you'll have to prepare the field if you want to sweep with it).
HP Fire allows you to hit Steel Pokémon like Ferrothorn or Scizor-Mega which disturbs our Mega.
Substitute will be there to avoid statuses and to scam the opponent by spamming this attack while waiting for the opposing Pokémon to be paralyzed. The investment prevents Rotom from breaking the clone with Hydro Pump.
Kaideos (Keldeo-Resolute) @ Choice Scarf
Ability: Justified
EVs: 252 SpA / 4 SpD / 252 Spe
Timid Nature
- Scald
- Hydro Pump
- Secret Sword
- Icy Wind
It's a very good threat to consider.
It's the best Pokémon with Choice Scarf, and it can also switch into many threats like Bisharp or Tyranitar.
Scald is there for its accuracy and because its burn is excellent in Gen 6.
Hydro Pump allows it to hit harder.
Secret Sword is its Fighting-type STAB move, allowing it to avoid being blocked by Pokémon like Chansey.
252 SpA 30 IVs Keldeo Secret Sword vs. 4 HP / 252+ Def Eviolite Chansey: 366-432 (57 - 67.2%) -- guaranteed 2HKO
Icy Wind provides speed control.
Adam Delamer (Garchomp) @ Rocky Helmet
Ability: Rough Skin
EVs: 252 HP / 164 Def / 76 SpD / 16 Spe
Impish Nature
- Stealth Rock
- Earthquake
- Dragon Tail
- Fire Blast
For our defensive core, we'll start with Tank Chomp.
It allows you to check many threats like Talonflame and Bisharp while also being able to weaken U-Turn users like Jirachi or Lando-T thanks to the Rough Skin + Rocky Helmet combo.
Fire Blast allows you to lure Steel-type Pokémon.
Investing in Speed allows you to outspeed Pokémon invested in outspeeding Jolly Tyranitar.
Investing in SpD gives Garchomp the Special Defense needed to survive powerful hits from Pokémon such as Mega Charizard Y, Gengar, Keldeo, and Mega Diancie, while still retaining the optimal amount of physical bulk.
Thor-Boyaux (Zapdos) @ Leftovers
Ability: Pressure
EVs: 252 HP / 60 Def / 180 SpD / 16 Spe
Calm Nature
IVs: 0 Atk / 30 Def
- Volt Switch
- Hidden Power [Ice]
- Roost
- Defog
Zapdos allows you to have a switch-in to Flying-type Pokémon like Tornadus-T, Mega Pinsir, Talonflame.
Volt Switch completes the core of Volt-Turn.
Hidden Power [Ice] allows you to have a pseudo-Boltbeam.
The given EVs maximize Zapdos's special bulk, allowing it to check powerful special threats, such as Keldeo and Gengar, as well as survive a +2 Return from Mega Pinsir after Stealth Rock damage and one round of Leftovers recovery while outpacing Adamant Bisharp. Leftovers is crucial to survive +2 Return from Mega Pinsir after Stealth Rock damage and increases Zapdos's overall longevity.
I'm open to your feedback. I hope you enjoyed this RMT.
How I came up with the idea for the team
This time, here's a team with more classic Pokémons. Although they only have one type in common, Heatran and a Steel- and Psychic-type Pokémon like Metagross-Mega only share a weakness to the Ground-type.One Pokémon complements both Pokémon well (and Serperior is the only Grass-type Pokémon in OU 6G (Ferrothorn would add a third Steel-type Pokémon, and it's not a Monotype team).
Then Scarf Keldeo is the best Revenge-Killer in the tier.
And finally, the Tank Chomp + Spe Def Zapdos duo.
