Scizor@Occa Berry
Swarm
Impish (+Def/-SpAtt)
EVs: 252 Hp/104 Def/32 SpDef/120 Speed
-Iron Defense
-Baton Pass
-Roost
-X-scissor
Sturdy lead, Iron Defenses increase his ability to take hits and can be Baton Passed. Roost for recovery and X-scissor for STAB, getting hits on Weavile and the like. Able to comfortably shake off Explosions, especially with Iron Defenses under his belt. Occa berry to weaken Fire attacks.

Gliscor@Leftovers
Hyper Cutter
Impish (+Def/-SpAtt)
EVs: 244 Hp/216 Def/48 SpDef
-Rock Polish
-Baton Pass
-Roost/Taunt
-Earthquake
244 Hp EVs allows for maximum Leftovers recovery, and the extra few points are fairly unnecessary anyway. Rock Polish to be Baton Passed, Roost for survivability (or Taunt to block Phazing/Hazing). Earthquake gets STAB.

Togekiss@Leftovers
Serene Grace
Calm (+SpDef/-Atk)
EVs: 232 Hp/192 Speed/84 SpDef
-Nasty Plot
-Baton Pass
-Roost
-Air Slash
232 Hp gives, again, maximum Leftovers recovery, with an extra point to allow 4 switch ins to Stealth Rock whilst leaving 1HP. The extra points from Hp went into SpDef. Nasty Plot benefits itself, adding power to Air Slash, which can hurt with the boosted Flinch rate, which helps to make up for the amount of pokemon who resist it. Once again, Roost for survivability.

Drifblim@Apicot Berry
Unburden
Calm (+SpDef/-Att)
EVs: 252 Hp/64 Def/80 SpDef/112 Speed
-Substitute
-Baton Pass
-Shadow Ball
-Thunderbolt
Surprisingly, one of the more strategic members of the team. Firstly, 252 Hp to give sizeable substitutes (126 Hp) and grant him survivability. 112 Speed EVs allows him to [barely] outrun Bulky Gyarados, i think, when it hasnt used DD yet. Thunderbolt was missing from the rest of the team, and so here it is, if only for Gyarados. When health gets low, the Apicot berry activates, increasing SpDef. This then Activates his ability Unburden, doubling Speed (incidentally allowing him to outrun a BulkyDos with 2 DDs running). These can then be Baton Passed on of course, as well as his substitutes which, With Iron Defenses, the Apicot SpDef boost and 126 Hp behind it, wont be breaking easily. He's able to stand a Hp (Ice) from Heatran, with no boosts going, with ~half Hp remaining.

Smeargle@Focus Sash
Own Tempo
Jolly (+Speed/-SpAtt)
EVs: 252 Hp/4 SpDef/252 Speed
-Ingrain
-Baton Pass
-Rapid Spin
-Seismic Toss
Its stats are just awful, so Speed was priority, since it doesnt do much else. Hp came after to help ensure some sort of survivability. Focus Sash was used for the same reason. Ingrain stops PHazing, and Haze is rare enough i think. Rapid Spin gets rid of spikes and whatnot, which i feel is more valuable than Spore. Seismic Toss makes up for the awful attack stat. I tend to stay away from movesets with no attacking moves, as i feel they are more likely to get trapped into uselessness when something like Taunt is used. Didnt want to set it as lead due to the number of leads running Taunt.

Glaceon@Leftovers
Snow Cloak
Modest (+SpAtt/-Att)
EVs: 200 Hp/56 SpAtt/80 SpDef/172 Speed
-Wish
-Baton Pass
-Ice Beam
-HP (Fighting)
Generally, this is what does most of the sweeping i find. The Ice/Fighting combination hits hard, particularly with Nasty Plots backing it, and hits every type for at least Neutral Damage. Wish can be Baton Passed, particularly helpful for Drifblim, allowing him to continue setting up Substitutes. 200 Hp EVs, again, allows the Stealth Rock switch ins and maximum Leftovers recovery. Its defenses are already fairly solid, so i invested EVs in SpDef instead, especially considering possible Iron Defense boosts. I'm not sure whether the Speed EVs are necessary or better spent in other areas, however, after a single Rock Polish or unburden boost it reaches into the 400s (416).
I really thought the EV spreads through and calculated them as best i could (although in most cases i can't remember the reasoning behind them) and tried to create imaginative sets. I'd appreciate any criticism/advice or anything that you're willing to give.
I apologise for the length by the way.
