Well, here's my team. I'm relatively new on this, so don't critisize too much if it's not good at all... But I'll be glad if you can help me, guys 
My team!
Bronzong @ Toxic Orb
Trait: Levitate
EVs: 252 HP / 4 Def / 252 SpD
Sassy Nature
- Stealth Rock
- Trick
- Earthquake
- Explosion
My lead, Bronzong, is the one who put rocks on the foe's field. It can also annoy some "choice sweepers", or just toxic someone (good at breaking some annoyers/walls, for example), with Trick and the Toxic Orb. Earthquake is for Magnezone, and Explosion to finish his job. It's who absorb the foe's Toxics. I'm thinking in a Ferrothorn for doing this job, or a Blissey with Stealth Rock.
Whimsicott @ Leftovers
Trait: Prankster
EVs: 4 HP / 252 Def / 252 SpD
Calm Nature
- Taunt/(Maybe a change for Stun Spore?)
- Encore
- Leech Seed
- Substitute
Ah, Whimsy. Just a headache. The one to cripple boost sweepers and walls. I usually change on it when a water type attack is aimed to my Chandelure. I have searched for a Swicheroo/Encore Whimsy, but it seems illegal.
Chandelure @ Life Orb
Trait: Flash Fire
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
- Overheat
- Energy ball
- Shadow Ball
- Psychic
My wallbreaker, but it surely will have problems with Blissey/Chansey. Wide coverage, a switch-in for Fighting, Normal and Fire attacks. Since it's a wallbreaker, I don't think a Timid Nature is useful. It's useful for Scizor who don't invest on Speed, or Forretress and Ferrothorn, bulky water types who don't have Aqua Jet (Gastrodon, Swampert, Jellicent)...
Hydreigon @ Choice Scarf
Trait: Levitate
EVs: 4 HP / 252 SpA / 252 Spe
Timid Nature
- Flamethrower
- Draco Meteor
- Focus Blast
- Dark Pulse
My revenge killer. It's just amazing. I'm thinking in a mixed one, though. Along with Bronzong, they're the one who switch-in on a Ground move. It has a good movepool, and I think this moveset is kinda useful. It have problems with Blissey/Chansey, and Jolly Scarf Terrakion/Mach Punch users (Conkeldurr). The last ones are tried to be predicted and aimed at Chandelure (keeping in mind Rock Slide and Stone Edge). I'm thinking on a Terrakion to do this job, but I'll miss Hydreigon's coverage.
Umbreon @ Leftovers
Trait: Synchronize
EVs: 252 HP / 4 Def / 252 SpD
Careful Nature
- Wish
- Payback
- Heal Bell
- Protect
The wisher and status remover of my team. It's typical. I don't know what to say exactly about it: it's just really useful for my team, specifically healing Hydreigon.
Magnezone @ Light Clay
Trait: Magnet Pull
EVs: 252 HP / 208 SpA / 48 Spe
Modest Nature
- Reflect
- Light Screen
- Volt Switch
- Hidden Power Fire
Its job is basically to trap dangerous Steel types, and set screens. Its resistance and natural bulk allow it to do its job easily. With 48 EV on Speed, it outspeeds 0 EV Speed Scizor. Maybe I should replace Hydreigon's object, or him, because the screens will be useful for setting up.
Maybe I've to replace Umbreon for a Vaporeon (0 EV/31 IV Special Attack Ice Beam OHKO Gliscor, 2HKO Hydreigon, and 2HKO Multiscale Dragonite). I dunno, I have a lot of ideas but I'm not really sure about them :/ A Mandibuzz for stalling? An Alomomola/Audino/Vaporeon for wishing? A physical wall like Tangrowth with Regeneration? I'll really appreciate your help, guys.
PD: Don't reccommend me unreleased/event/hack things, please, because I can't get them :b
