Like Dust Elemental said, EV placement is just a bit out of whack, placing 252 in HP serves better than splitting EV's into the defenses, it also allows you to maximize bulk in one of the defenses, giving you better walling capabilities against a sweeper (most tend to lean either between the physical or special)
also playing against your friends Double team may be allowed, but once you decide to competitively battle, any Evasion increasing move is banned
Sableye
not really familiar with the it, but it's lack of weaknesses doesn't overcome it's low base stats IMO, the only sets i can really think of, are a toxi-trapper, or a sucker taunter, both of which can be done by better pokemon, but if you like using Sableye don't let me stop ya
biggrin Toxi-Trapper:
Sableye@Leftovers
Impish
Keen Eye/Prankster (this is a Dream World Ability, and i don't know if it's legally available yet)
252HP/4Atk/252Def
Toxic
Mean Look
Recover
Protect
(Complete taunt bait, but if you can trap a wall you should be able to take it out)
Sucker Taunter
Sableye@Life Orb
Adamant
Keen Eye/Prankster
252HP/252Atk/4Def
Taunt
Sucker Punch
Recover
Low Sweep
Bronzong
Unless you plan on running a dedicated trick room team just deciding to throw Trick Room out if it suits you won't help you much, once those 4 turns are up (using trick room counts as one turn), and Bronzong is gone, all your pokemon who take advantage of TR end up getting outsped, you usually need at least 2 Trick Roomers for it to be effective, though if you wanted to run a dual screens set that could work for your team a lot better
something like this
Bronzong@Light Clay
Sassy
Levitate
252HP/4Atk/252Sp Def
(0 speed IV)
Light Screen
Reflect
GyroBall
Rest/Stealth Rock/Toxic
Light Clay will allow your dual screens to last 8 turns, the EV spread maximizes your bulk to take special hits, Gyroball is Bronzong's best attacking move, usually getting over 100 in base attack before stab (if your speed IV is around 0) The last move slot depends on what you want to do
Spiritomb
Another pkmn i'm not too familiar with, though running both shadow ball and dark pulse is a little redundant, since they hit the same things for super effective, i might suggest running a physically defensive nature, like Impish, and giving it an EV spread of 252HP/144Def/116Sp Def or splitting the last 116 among Sp Def and Sp Atk however you want, if you drop Nasty plot for Calm mind, you boost both your sp Atk and Sp def 1 stage each, add Will-0-Wisp, and you cut any physical sweepers power in half, giving you 1 spot for an attacking move and another for a recovery move, or 2 attacking moves if you want
Drapion
another pkmn i don't use too often
sweatdrop lol, but if you're using him as you're sweeper than having him use toxic spikes wouldn't be too effective, sniper would be a better ability IMO getting a boost if you crit, would help out much more than preventing a Crit,
Drapion@Life Orb/Leftovers
Jolly
Sniper
4HP/252Atk/252Speed
Swords Dance
Night Slash
Ice Fang
EarthQuake
again don't know if this set will work, since i don't normally use Drapion lol
Palkia
this one is uber if you ever decide to use it for competitive play, but drop ice beam since coverage is redundant, replace it with Surf or Hydro Pump, to get the most out of the lustrous orb, and drop earth quake for either Earth Power, or Thunderbolt, whichever you feel you need to have on your team
Elektross
It actually has a great movepool, it's biggest weakness is speed,
you can run a physical set:
@Life orb/Expert Belt
Adamant
4HP/252Atk/252Speed, or if you don't care about its lack of speed, swap the EV's between HP and Speed, to allow you to take a hit
Levitate
Wild Charge
Dragon Claw
Crunch
Brick Break
a special Set
Modest
same ev's except atk goes into sp atk
Levitate
Thunderbolt
Flamethrower
Grass Knot
Charge Beam/Volt Switch
or a Mixed Set
Lonely/Naughty/Mild/Rash
Ev spread:252 in both attacks if you don't care about speed, otherwise, max the attack that the nature boosts, and distribute the rest between the other attack and speed/HP
Thunderbolt
Flamethrower
Dragon Claw
Brick Break
i don't think i'm the greatest at giving suggestions, but i hope i helped nonetheless Good Luck
