RMT: Let the Battle Begin
This is the team I’ve used for a time now and I really want some help. This teams job is to weaken the enemies team to the point where Lucario can sweep or Flygon can revenge kill by using LOTran and CBScizor to force switches. Bulky Rotom as a check to many pokemon and lure for Dark/Rock/... moves for lucario to set up.
Title means that I just started competive battling and this is my first succesful team.
Celebi

Timid
Occa Berry
80 HP / 252 SpA / 176 Spe
~ Leaf Storm
~ Earth Power
~ Stealth Rock
~ U-turn
Made Celebi my lead. I first was not sold on this but in the end I started to like this. It sets up Stealth Rock versus anything without Taunt or not named Azelf. It's useful later on as a scout or a check to Gyarados as it can take quite a beating. It even has a chance defeating Heatran with Occa Berry.
Top 15 lead: Azelf: lose if it uses U-turn ( it KOs) otherwise I U-turn out to Scizor.
Aerodactyl: 2 times Leaf Storm, it loses if it Taunts.
Swampert: KO with Leaf Storm.
Machamp: Stealth Rock, U-turn on Ice Punch or Payback or switch on D-punch.
Metagross: 2KO it with Earth Power or switch to Rotom to take the Explosion.
Jirachi: tricky, if it Tricks switch otherwise Stealth Rock.
Infernape: Stealth Rock while Fake Out + FB failed to KO due to Occa Berry. Then Switch.
Ninjask: switch to priority user, most of the time Scizor.
Roserade: outspeed non-scarf and Earth Power, take sleep and switch to Scizor for easy KO.
Hippodown: Leaf Storm for the KO.
Tyranitar: Stealth Rock, scout his item, if slower than Celebi Leaf Storm for damage, switch to Scizor and BP.
Heatran: KO with Earth Power, easier than Infernape.
Smeagle: outspeed non-scarf and Leaf Storm, same as Roserade.
Uxie: Stealth Rock and U-turn.
Starmie: Leaf Storm for the KO (without sash).
Heatran

Naïve
Life Orb
252 SpA / 4Spd / 252 Spe
~ Fire Blast
~ Earth Power
~ Hidden Power Grass
~ Explosion
Life Orb heatran with Explosion and HP Grass for Bulky Waters like Swampert and Vaporeon. Just FB away untill everyone is in range of a revenge kill by scizor or Flygon. This can change to something who can counter other Heatran but its damage and bulk is to good to give up.
Flygon

Jolly
Choice Scarf
4 HP / 252 Atk / 252 Spe
~ Outrage
~ Earthquake
~ U-turn
~ Stone Edge
My Revenge killer in place of Rotom. Isn't Pursuit weak and Dragon revenge killer. If Rotom should die before Gyarados is dead, Flygon comes in on the Dragon Dance Outrages, forcing it out or weakening it, let Flygon die, switch to Lucario and Revenge with ES. This team needs momentum and with U-turn Flygon becomes a very fast scout.
Flygon is important throughout the battle with its speed, coverage, and scouting abilities. I won't use him early game, only mid- and endgame, he needs all his health that he can get to the end to survive priority like unboosted ES of Luke.
Scizor

Adamant
Choice Band
168 HP / 258 Atk / 80 Def / 32 Spd
~ U-turn
~ Bullet Punch
~ Superpower
~ Pursuit
My scout and revenge killer. Checks so many things, like Gengar, Tyranitar and Salamence. Forces enough switches in a match until everyone is weakened enough and in range of Bullet Punch. Early scout and revenges leads that Celebi can't take on like T-tar, Azelf, Ninjask, Roserade and much more.
Need a better spread for Scizor, a bulky one plz.
Rotom-H

Bold
Leftovers
252 HP / 168 Def / 88 Spe
~ Thunderbolt
~ Will-o-Wisp
~ Rest
~ Sleeptalk
My Gyarados and Scizor counter. Can check other things aswell like Gliscor and Celebi. Made it the Resttalk set as Scarf isn't needed anymore with Flygon. Now with Recovery Rotom can stay alive and check Gyarados, Gliscor, Swampert, Skarmory and lots of other stuff.
Lucario

Adamant
Life Orb
4 HP / 252 Atk / 252 Spe
~ Swords Dance
~ Close Combat
~ ExtremeSpeed
~ Crunch
My late game cleaner and second priority if Scizor dies.
Can set up on Choiced Dark, Rock and sometimes Dragon (Flygon) moves.
Its just wonderful that lucario has so much resists and chances to come in.
A resist to Stealth Rock is always a plus and his power is huge.
Most swampert with 60 percent stay in on Luke while getting beaten by LO Adamant Close Combat.
Weaknesses:
Heatran and other Fires.
Kingdra: if it can set up I'm done but if its a Resttalker just wear it down with Leaf Storm or set up Luke.
Flygon/Salamence/Dragonite: if somehow Scizor dies and the Dragons are still alive late game it just game there.
Anything that just KOs my core is a threat to the team, in this case I just play mindgames and switch if they are holding life orb.
Now they are less a problem with Flygon.
So this was the team, I know it got some glaring weaknesses but most times I can play around this. Rate or Hate plz
Conclusion: its an more offensive oriented team with Bulky pokemon like Celebi and Rotom to counter Key oppenents. Scouting Lukes counters with Uturn and Expose of them.
Edit: Made SubTran LoTran, Celebi my lead, Flygon my Revenge Killer and Rotom Bulky. Anymore rates are always welcome and thanks for those who had already rated!
thoughts: making Rotom Resttalk because Painsplit isn't enough to heal.
Stone Edge on Luke over Crunch and making him Jolly or using T-wave somewhere (not needed)
