This was my first attempt at creating an X/Y OU team, as I normally play lower tiers like RU or PU. I knew I couldn't make a team that could counter everything in the Meta, so I picked a few Pokes who I felt synergized well together. This team was built around Mega Heracross, who I have never used competitively before, and wanted to try out.
Heracross @ Heracronite
Ability: Guts
EVs: 200 HP / 252 Atk / 56 Spe
Adamant Nature
- Swords Dance
- Close Combat
- Pin Missile
- Rock Blast
Here is the Pokemon I decided to build my team around. I'm using Moxie for quick kills before I mega-evolve, allowing me to obtain a nice attack boost. WSD is mostly used on predicted switches, allowing Heracross to destroy the Pokemon that switches in. CC is the standard move on this set, dealing immense damage to those who don't resist it, and getting an OHKO on Blissey/Chansey. Pin Missile is the secondary STAB attack, and hits Pokemon like Slowbro or Latios/Latias. Rock Blast takes advantage of Skill Link to hit 5 times, and gives Heracross a last resort for Flying types. I'm running 52 EVs to outspeed neutral Base 80's, while the rest go into bulk and attack.
Scizor @ Shed Shell
Ability: Technician
EVs: 248 HP / 44 Atk / 116 Def / 100 SpD
Adamant Nature
- Defog
- Roost
- Bullet Punch
- U-turn
Scizor is a Pokemon I added to the team to A) create a VoltTurn core, and B) to have a bulky defogger with access to priority. Scizor works great for getting rid of those nasty hazards, and uses it's Technician-boosted Bullet Punch to deal loads of damage to Pokemon like Gardevoir and Sylveon. Roost is there for recovery, adding to Scizor's longevity. This Pokemon was originally banded, but I changed it to a bulky defogger as my team had no way of getting rid of hazards, and Heracross was a better Pokemon for pure attacking anyway. The EV Spread is for standard for a Bulky SD variant, however it helps with the hazard clearer set I am running.
Heatran @ Air Balloon
Ability: Flash Fire
EVs: 248 HP / 8 SpA / 252 SpD
Calm Nature
IVs: 0 Atk
- Stealth Rock
- Lava Plume
- Earth Power
- Roar
Heatran is the hazard setter of the team, and burns with opponents with Lava Plume and Roars out setup sweepers who Heatran can take a hit from. Earth Power is there so I don't get walled by other Heatran and Gardevoir who Trace my Flash Fire. This is the special half of my defensive core, and also switches in on Pokemon who try to hit Scizor with a fire move. Once the Air Balloon is broken, Heatran relies on switches into the other half of the defensive core...
Rotom-Wash @ Leftovers
Ability: Levitate
EVs: 248 HP / 212 Def / 44 Spe
Bold Nature
IVs: 0 Atk
- Volt Switch
- Hydro Pump
- Will-O-Wisp
- Pain Split
Ah, Rotom Wash. One of my favourite Pokemon to use in OU. This Rotom is my main check to the physical attacks in OU, like Talonflame, and cripple them with Will O' Wisp, if the RNGods aren't being mean to me (missed 4/5 of my last Will O' Wisps). Volt Switch is for my VoltTurn combo, and is used to keep momentum on predicted switches. Pain Split is just for recovery, and stealing health from Chansey whenever I get the chance. 0 Atk IVs are used just to minimize damage taken from Foul Play, no matter how rare that attack is in OU. Rotom-W pairs up really well with Heatran, and the two make for a great defensive combo. 44 Spe EVs are used to outspeed Azumarril, and dish out damage or burn it.
Sylveon @ Leftovers
Ability: Pixilate
EVs: 248 HP / 252 Def / 8 SpD
Bold Nature
IVs: 0 Atk
- Hyper Voice
- Wish
- Toxic
- Heal Bell
Sylveon is my support Pokemon, healing statues from my other Pokemon and healing them with wish. Sylveon also works great to take out some of the Dragon types in OU, other than Defensive Latias. Toxic is for putting Pokemon on a timer, and is a good move altogether. I am considering removing Toxic for Protect, however, as Protect would help gain extra Lefties recovery and help stall burn/poisoned Pokemon.
Greninja @ Life Orb
Ability: Protean
EVs: 4 Atk / 252 SpA / 252 Spe
Hasty Nature
- Surf
- Ice Beam
- Hidden Power [Grass]
- Gunk Shot
Oh, Gamefreak. "Let's make a Pokemon with near perfect coverage and the ability to change type!" Greninja is insanely good now with Gunk Shot (via ORAS Tutor), and a diverse moveset like this helps Greninja score many powerful hits on many Pokemon. I had Dark Pulse over HP Grass before, but my lack of a Grass move on this team encouraged me to change it. I'm running Surf for a mix between power and accuracy, as I find Scald too weak, and Hydro Pump inaccurate. Gunk Shot also OHKOs many of Greninja's checks from X/Y, such as Clefable. Greninja usually comes in from a U-Turn/Volt Switch kill to reduce the damage it takes.
I've had many fun battles with this team so far, and it honestly works very well as long as I play well and make good predictions. I'll accept any criticism, and am open to make any changes to this team to make it even better. As long as you provide good reasons, I'll even consider replacing certain Pokemon or the roles each Pokemon plays for the team. Thank you for reading, and remember, Salamence is a piece of shit!
EDIT: Megahorn was changed to Pin Missile, as it has better accuracy. Scizor's EV Spread was changed to a bulky SD set, and Leftys was changed to Shed Shell as well, giving me a free switch into Heatran to counter Magnezone. Rotom-W was given 44 Spe EVs to outspeed Azumarril, as a Burn or damage on it would be very nice. Sylveon was also given more defense EVs in order to make its defenses mixed.
