Hi guys this is my first RMT and it features Terrakion, arguably the most broken Pokemon in the current metegame. It has been my most successful team by far, and has reached 1200, but I think could go further. I would really like some help though. My main problems have been against some hyper offense teams, as well as rain teams when Rotom-W and Celebi go down. It is quite solid in my opinion, but does need some polishing.
Heatran
Nature: Timid
EV's: 4hp, 252sp.att, 252spe
Item: Air Balloon
Ability: Flash Fire
Flamethrower
Earth Power
HP Ice
Stealth Rock
Heatran is my sun counter. He has great coverage, and with an Air Balloon laughs in the face of Dugtrio and the like. I originally had the specially defensive set, which was still great, but this one packs a bigger punch, and much better coverage. He can still reliably set up SR, and still easily switch in on Scizor and standard Tar. HP Ice takes care of Gliscor who try to set up, while Earth Power takes out the fire types on sun teams, as well as Infernape and opposing Heatran.
Celebi
Nature: Modest
EV's: 188, 252sp.att, 68spe
Item: Leftovers
Ability: Natural Cure
Nasty Plot
HP Fire
Giga Drain
Psychic
Nasty Plot Celebi is one of the best sets I've ever used. It is just so underrated. Not even Blissey can beat it(I've done it before). Nasty Plot just sends his sp.att skyrocketing, while Giga Drain can heal back his health. HP Fire decimates Scizor, who always tries to U-turn away and gets killed, as well Ferrothorn and Forretress. Psychic is absolutely necessary in dealing with Conkeldurr, which is one of Celebi's main reasons for being on the team. Celebi really helps against rain teams-taking out pretty much all of the standard members apart from Dragonite or Tornadus. The speed ev's outspeed all Scizor's apart from Scarfed sets, which I've never encountered
Rotom-W
Nature: Timid
EV's: 4hp, 252sp.att, 252spe
Item: Choice Scarf
Ability: Levitate
Volt Switch
Hydro Pump
Thunderbolt
HP Ice
Rotom-W is my first revenge killer. When combined with Celebi, I can usually beat rain team, and is great at taking out DD Gyarados and Tornadus, as well as Starmie and Politoed. Hydro Pump is his most powerful move, and does heavy damage to Tyranitar and Heatran. HP Ice hits the Dragons hard, while Thunderbolt allows me to seriously damage Rain teams without needing to switch, as well as having the ability to 1HKO Gyarados. He was originally a bulky variant, but I was having trouble with speedier Pokemon, and Rotom-W now works much better as a revenge killer.
Skarmory
Nature: Impish
EV's: 252hp, 224def, 32spe
Item: Leftovers/Shed Shell
Ability: Sturdy
Brave Bird
Whirlwind
Spikes
Roost
Originally, I had a big weakness to powerful dragons like Haxorus, Landorus, Gyarados and Scizor. Thankfully, there is a Pokemon that checks all of these-Skarmory, the best physical wall in the game. The set is pretty standard, but Spikes is the most important move. Against the likes of rain teams, it is difficult to get Heatran in to set up Rocks. After a kill, Skarmory can then switch in and set up at least one layer, which goes a long way in stopping the likes of Heatran, Politoed and Gastrodon. Brave Bird provides a STAB move to take out Breloom, Heracross and Swords Dance Virizion. Roost gives me healing power, while Whirlwind provides me phazing power which I lost when Heatran was changed to a more offensive version.
Tyranitar
Nature: Jolly
EV's: 4hp, 252att, 252spe
Item: Choice Scarf
Ability: Sand Stream
Stone Edge
Crunch
Pursuit
Superpower
Tyranitar is my replacement for Landorus, who was here previously. He is Terrakion's partner in crime-softening up his counters so he can sweep. The main reason for Tar though is to counter weather teams-in particular, sun. He stops the fearsome weather sweepers cold, which could be devestating to the rest of the team. Terrakion really benefits from the special defense boost too. He doesn't normally lead, but does against Baton Pass teams since he destroys Espeon, who I despise.
Terrakion
Nature: Jolly
EV's: 4hp, 252att, 252spe
Item: Rock Gem
Ability: Justified
Substitute
Swords Dance
Stone Edge
Close Combat
Terrakion is who the team was built around, and with good reason. He is an absolute monster. The SubSwords Dance set looked really good, so I decided to try that, and I was not disappointed. He can do huge damage even without a Swords Dance boost, and when he does, he kills everything. I was using Life Orb, but Rock Gem allows him to OHKO Gliscor at +2, which was very handy. Out of all the others, he does by far the most damage.
So, that's the team. Hope you enjoyed!
