This is the team that I've put together for battling online in Pokemon X/Y. It works decently well for the most part but it has a couple weaknesses that someone might be able to suggest a good fix for.
Dragonite @ Lum Berry
Ability: Multiscale
EVs: 4 HP/252 Atk/252 Speed
Adamant Nature
-Dragon Dance
-Outrage
-Earthquake
-Roost
One of my favorite pokemon ever and a flexible threat to enemy teams. The neutral coverage of Dragon and Ground means very few pokemon wall Dragonite effectively, and Multiscale almost guarantees at least one Dragon Dance. I regularly sweep unsuspecting teams 6-0 because of how big a threat a +1 or +2 outrage can be. Lum Berry gets me around the odd Will-o-Wisp or Thunder Wave that would try to shut Dragonite down and lets me grab another Dragon Dance to ensure a sweep. Outrage is more dangerous than before with Fairy pokemon being immune to it but with Team Preview I usually have a good idea of when I can safely use it.
Lucario @ Lucarionite
Ability: Steadfast
EVs: 4 HP/252 Atk/252 Speed
Jolly Nature
-Swords Dance
-Close Combat
-Bullet Punch
-Crunch
Lucario rounds out Dragonite's coverage to create a strong offensive core that can break most teams. His base 112 speed after mega evolving helps keep Mega Kangaskhan in check which, while banned in Smogon OU, is still very popular in online battles. Adaptability and his new base 145 Attack mean that Swords Dance isn't needed to threaten a KO on many pokemon, but if I do sneak a boost in then the game is usually over.
Azumarill @ Choice Band
Ability: Huge Power
EVs: 252 HP/252 Atk/4 Def
Adamant Nature
-Aqua Jet
-Waterfall
-Superpower
-Play Rough
Azumarill is a solid offensive threat that, unlike Dnite or Lucario, requires no setup to do its job. The threat of being instantly KOed by a CB-boosted aqua jet can force out fast threats like Talonflame and open the other team up for free punishment from one of Azumarill's other powerful attacks, wearing the enemy team down over time.
Gengar @ Black Sludge
Ability: Levitate
EVs: 4 HP/252 SpAtk/252 Speed
Timid Nature
-Shadow Ball
-Sludge Bomb
-Focus Blast
-Substitute
Gengar was originally selected to be an extra check on Mega Kangaskhan without Crunch since all of its typical attacks are ineffective and I can stall out Sucker Punch with Substitute. The introduction of Fairy pokemon finally allows Gengar to make good use of his Poison STAB and Sludge Bomb is the perfect move for the job, sporting a solid base power and a 30% poison chance for punishing pokemon that try to wall Gengar.
Chansey @ Eviolite
Ability: Natural Cure
EVs: 252 HP/252 Def/4 SpDef
Bold Nature
-Softboiled
-Toxic
-Seismic Toss
-Aromatherapy
Chansey is the team cleric, keeping the team status-free with Aromatherapy while sponging special threats with ease. Put bluntly, I chose Chansey over Blissey because getting extra Leftovers is really hard. However, Chansey definitely eats physical attacks better than Blissey thanks to Eviolite meaning I can switch it in on a few more pokemon than I normally could.
Ferrothorn @ Leftovers
Ability: Iron Barb
EVs: 252 HP / 48 Def / 208 SpD | 0 Speed IV
Relaxed Nature
-Stealth Rock
-Protect
-Leech Seed
-Gyro Ball
Ferrothorn rounds out my defensive core alongside Blissey, providing the wonderful defensive benefits of a Steel typing while being able to set up Stealth Rocks for my team and stall out some offensive threats with leech seed + protect.
========================================
TEAM WEAKNESSES
Note that these are only weaknesses I have personally observed, you may find that there are more given that I'm not too great at this game.
1. Aegislash is a huge problem. I switched from Fire Punch to Earthquake on Dragonite to deal with the Brave Fencer variant but without Dnite I have trouble beating this thing.
2. 3 fighting weaknesses, including both members of my defensive core. This is sort of rounded out by 2 fighting resistances and an immunity but if the wrong fighting type gets set up then I basically lose.
3. Most of my offensive line-up is physical, which means that a good physical wall can cause problems for me. I'm thinking of replacing Azumarill with something more specially-oriented but the loss of a priority move would sting a little.
4. Speaking of priority moves, the team has trouble with very fast threats. +1 Dnite can outspeed a lot of things but if there's something really fast like a Scarf user or if I can't pull off a Dragon Dance then I can only fall back to a base 112 Mega Lucario or a base 110 Gengar which are fast but not exceedingly so. Bullet Punch and Aqua Jet mitigate this problem a little but their BP isn't high enough to ensure a OHKO on every fast thing out there, especially since their super effective coverage is a little lacking.
