I did this a while ago, but I forgot to put descriptions on my Pokémon. I'm re-uploading this so people can see how I use this team.
Luna (Clefable) (F) @ Sitrus Berry
Ability: Unaware
Level: 50
EVs: 252 HP / 72 Def / 184 SpD
Calm Nature
IVs: 0 Atk
- Follow Me
- Moonblast
- Icy Wind
- Protect
Clefable is the Follow Me user. It allows the other Pokémon on the team to set up stat boosts. The given ev spread and calm nature allows it to tank, and the situs berry adds longevity. Moonblast is mainly if your other Pokémon finished setting up and if there is a Dragon on the other team. Icy Wind lowers both opponents' speed stats, but odds are that Clefable will still have lower speed (Thunder Wave can alternatively be used, but it only hits one Pokémon at a time, and Ground types are immune). However, it allows other teammates to outspeed some threats.
EZ-Bake (Rotom-Heat) @ Leftovers
Ability: Levitate
Level: 50
EVs: 248 HP / 40 Def / 220 Spe
Bold Nature
IVs: 0 Atk
- Pain Split
- Thunder Wave
- Volt Switch
- Overheat
Rotom is mainly here for switch-ins and type coverage. It can tank decently well, and it has levitate. This prevents it from taking Earthquake from Landorus, making it another good pair to open with. Pain Split is for when Rotom gets low on health. Thunder Wave lowers speed, although Will-o-Wisp and also be used for physical attackers. Overheat is a strong STAB move, but it harshly lowers Special Attack. Volt Switch switches Rotom out and removes the Special Attack drop.
Quill (Chesnaught) (M) @ Salac Berry
Ability: Bulletproof
Level: 50
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Belly Drum
- Substitute
- Drain Punch
- Seed Bomb
Chesnaught performs its best when with Clefable. With Substitute and Belly Drum, Chesnaught gains a free protection and maxes out its Attack stat, respectively. After both of these moves are used, it is left at 25 percent health. With the given EVs, the Salac Berry will activate, boosting his speed and allowing him to sweep effectively. Drain Punch and Seed Bomb will most likely OHKO, even if they're not very effective. Drain Punch can also recover health. With Clefable's Follow Me, it can set up undisputed, becoming a massive wall breaker and sweeper.
Swordsman (Aegislash) (M) @ Weakness Policy
Ability: Stance Change
Level: 50
EVs: 252 HP / 252 Atk / 4 SpD
Adamant Nature
- King's Shield
- Swords Dance
- Shadow Claw
- Iron Head
Many Pokémon can fill this slot for type coverage, but I put Aegislash here for Ghost types. King's Shield protects attacks and can potentially lower the target's Attack if they use a contacting move. Swords Dance boosts Attack, and if Clefable uses Follow Me, He can potentially get maximum Attack. Also, if a Ghost type hits Aegislash while setting up, Weakness Policy will activate, boosting Attack even more. Then Shadow Claw and Iron Head are main STAB moves. Adamant is run instead of Quiet just in case of a Trick Room team.
LandGuy (Landorus-Therian) (M) @ Life Orb
Ability: Intimidate
Level: 50
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Earthquake
- Rock Slide
- Superpower
- Protect
Landorus is very good on this team. With Jolly nature and a Life Orb, it can outspeed many threats and still do a lot of damage. Earthquake is STAB and won't hit Chansey and Aegislash if they use Protect and King's Shield, respectively. Rotom also has Levitate, making it immune. Rock Slide and Superpower are run for coverage, and Protect is run just in case you need an extra turn for stalling out weather or Trick Room.
Cutlery (Scizor-Mega) (F) @ Scizorite
Ability: Technician
Level: 50
Shiny: Yes
EVs: 252 Atk / 4 Def / 252 Spe
Jolly Nature
- Swords Dance
- Bullet Punch
- Superpower
- Bug Bite
Scizor is the Mega and is mainly for Fairies. With Jolly nature, it becomes decently fast, but nothing special. Swords Dance boosts attack and can be paired up with Follow Me. Bullet Punch is a powerful priority STAB move with Technician. Superpower is for a very powerful attack, and Bug Bite is Technician boosted and eats the opponent's berry. This is useful if you're facing a Pokémon that commonly runs a Sitrus Berry. It can also be used on Clefable if it's about to die and Scizor needs the health.
