I've used this team for a long time, but I'm soon to be moving on. Let me know what you think, and what I could have done better.
A quick overview:
I like the synergy of the teammembers, and the fact that Toxic Spikes means nothing to me and this team is fairly comfortable in a Sandstorm. I have a pokemon immune to Thunder Wave, and another to absorb Will-O-Wisp, so Sleep is the only status I worry about. Most of the team are fairly bulky, but this isn't a dangerously offensive team. The main problem I see and constantly deal with is predictability. For teh most part these pokemon are by-the-books, so I struggle to catch my opponent off-guard.
Focus Sash
Modest
104 Defense/252 Special Attack/154 Speed
Speed Boost
-Protect
-Hypnosis
-Bug Buzz
-Air Slash
My used-to-be favorite lead. I'm leaning less towards Hypnosis since it dropped to 60% accuracy in Platinum. He still performs his job well and often dispatches enemy leads without priority moves. Bug/Flying has surprising coverage for at least neutral damage.
Leftovers
Timid
130 HP/128 Special Attack/252 Speed
Levitate
-Dragon Pulse
-Recover
-Calm Mind
-Reflect
Latias is the backbone of this team, working as a physical and mixed wall, providing Reflect support, and making a powerful tank given a few rounds of Calm Mind. Weaknesses are covered by Heatran and Magnezone. Played correctly, Latias is extremely difficult to be taken down without status moves. Once Magnezone removes enemy Steel-types, Latias can Calm Mind-tank with ease, since Dragon Pulse will do at least neutral damage.
Leftovers
Modest
40 HP/252 Special Attack/216 Speed
Magnet Pull
-Thunderbolt
-Hidden Power <Ice>
-Substitute
-Magnet Rise
Magnezone works here as a part-tank, part steel killer. He is instrumental in softening up my opponent for Latias to tank through his team, and HP Ice consistently proves its use as a surprise for Dragon sweepers trying to set up or revenge kill.
Leftovers
Impish
252 HP/40 Defense/218 Speed
Sand Veil
-Earthquake
-Ice Fang
-Stone Edge
-Roost
Gliscor works as my physical wall to switch in to absorb hits when I don't have time to set up Reflect. His Water weakness is covered by Latias, and Ice is covered by Magnezone and Heatran. I've considered using Stealth Rock here, but I don't have any pokemon with a powerful Ice attack, so I want at least two to hold Ice (Gliscor and Magnezone) and no other poke on my team has a Rock move.
Hasty
6 Attack/252 Special Attack/252 Speed
Fire Blast
Earth Power
Hidden Power <Electric>
Explosion
Heatran is my revenge killer. HP Electric is for the notorious Gyrados, who will often be switched into Heatran to set up for a sweep, or just knock out Heatran. I either predict it incoming (if I've seen Gyrados before) or switch Heatran in on the Dragon Dance. My numerous Levitators/flying type make avoiding Earthquakes easy.
Life Orb
Adamant
6 HP/252 Attack/252 Speed
Technician
-Bullet Punch
-Bug Bite
-Brick Break
-Swords Dance
Finally, we have Scizor, the amazing sweeper. Most of my team are SpAtkers, so I went with a physical sweeper to make the team fairly balanced. His good resistances and decent bulkiness (as far as sweepers go) give him ample opportunities to set up near the end of the battle. His 4x fire weakness works as bait for getting Flash Fire on Heatran after he revenge-kills early on.
