Man its been a while since I've made an RMT. But this is the team I have been using, and its gotten me into the top 50! (read siggy :p) with about a 90% win rate. This team is balanced, with only 1 setup sweeper, but in general is offensively oriented. Between the entire team there are a lot of resistances and immunities, and the team has great synergy, how else would this team remain nearly unchanged? I feel as this team cannot really go anywhere but I'm going to throw out a shout to the Smogon Community!
A quick glance:






In general this team leans towards the special side, with 4 special attacker, 1 physical, and one mixed (if swampert really counts as mixed xD)
Closer Look:

Azelf@Expert Belt
Levitate
140 HP/116 SpA/252 Spe
Naive Nature
Flamethrower
Grass Knot
Taunt
U-turn
Azelf is my preferred lead, and it recently took #1 in lead usage.This is not a suicide lead like most people expect, but an anti-lead. Grass Knot here handles Swampert, and Flamethrower handles Metagross and Scizor switchins, assuming that because I have Grass Knot I don't have a fire move. Grass Knot can also do minimum 45% to a Max/Min Tyranitar, and guarantees a 2HKO against 80/Min with the given EVs. Taunt handles many non-standard leads, like Thunder Wave Togekiss, and is also useful in forcing the occasional blissey switchin to attack. It also shuts down Smeargle leads. U-turn is to switch in a bad position, but it also breaks sashes off Infernape and Aerodactyl, as well as handling some pokemon like celebi or starmie.
Several other moves have caught my attention for the Taunt spot though. Ice Punch (alas Azelf does not learn Ice Beam) can handle Salamence and various dragon switchins, against which I am near helpless against. The other is explosion, which lets me go out with a boom and OHKO almost everything. Thunderbolt gets neutral coverage against a lot of things, mainly Heatran which any set would struggle with, but would still not help against Salamence. Overall I rarely find myself using Taunt anyways, but there have been a few situations where I have found myself thanking myself for putting Taunt.
Expert Belt is used over Focus Sash to guarantee the OHKO on Swampert, as Azelf only OHKOs 50% of the time without, a chance which I am not taking. It also allows Azelf to take on Metagross without having to use Fire Blast. Therefore, only the EVs necessary to OHKO swampert are put into Special Attack and the rest are put into HP, and pretty much no lead OHKOs azelf anyways without a critical hit.

Magnezone@Leftovers
Magnet Pull
44 Atk/212 SpA/252 Spe
Rash Nature
Substitute
Thunderbolt
Hidden Power [Grass]
Explosion
Magnezone was put in this team because it could support so much of my team. First of all it has great "Lead Synergy" with Azelf, meaning that it can take the leads Azelf can't, mainly Meteor Mash+Bullet Punch Metagross and Empoleon. It can handle the Steels that kill Latias and Rotom (metagross, scizor). It also handles Skarmory and Empoleon pre-Agility. It also serves as one of my defensive Steels, and is often the thing I go to to absorb sleep. I chose the Substitute version over the Scarf version because I do not like the Scarf version. With substitute I can set up on Scizor locked on Bullet Punch, and nail switchins hard. Thunderbolt hits hard with Magnezones Attack, and serves as the main attack. It does minumum 60% to Salamence, though on average SR + Thunderbolt + Life Orb recoil is enough to kill a Salamence. Hidden Power Grass is here, partially because I had used it to great success on an earlier team, and it handles Swampert. Hidden Power Ice is not necessary since Thunderbolt hits most dragons save Flygon neutrally anyways. Explosion is new on this set. Previously the team had problems taking down Blissey, and Explosion does just that, while the Magnet Rise version could not. Most people expect Substitute= it has Magnet Rise, which is not true and nets me surprise kills. It also handles Latias which this set could not otherwise handle.
The EVs yield max speed, the main purpose of which is to handle Empoleon. The Attack EVs are such that Stealth Rock + Thunderbolt + Explosion will KO a Blissey, though most of the time I'll Thunderbolt/Substitute multiple times to scout for Protect and lure them into a false sense of security.

Swampert@Leftovers
Torrent
252 HP/252 Def/4 SpD
Relexed Nature
Stealth Rock
Earthquake
Ice Beam
Roar
Since my lead was not a Stealth Rocker, I needed a Stealth Rocker, preferably one that could fill in many holes in my team. The first option I had was a support Gliscor, who could provide electric and ground immunities and check threats such as Lucario and Heatran. However, Gliscor had a few points that made it an inferior choice to Swampert. Swampert has often provided a very useful electric immunity as well, and it serves as my reliable phazer. It resists Heatran's Fire Blast and checks Salamence and Lucario. Swampert is also my first go-to pokemon to scout a threat, as it is incredibly hard to take down without being totally obvious. The moveset is simple, Stealth Rock for hazards, Earthquake is STAB and Ice Beam checks Salamence. Roar is for phazing and scouting purposes. The EVs are for maximum physical bulk.

Rotom-h@Choice Scarf
Levitate
40 HP/252 SpA/212 Spe
Timid Nature
Trick
Thunderbolt
Shadow Ball
Overheat
Rotom-h serves as one of the glues to my team. It provides a ground, fighting, and normal immunity, and fills up many holes in my team. Rotom checks many threats, Lucario, Latias, Gengar, Blissey, Skarmory, Gyarados, Scizor, the list goes on and on. Scarf Rotom has been one of my favorite revenge killers. Between Thunderbolt, Shadow Ball, and Overheat, it gets neutral coverage against pretty much the entire metagame with 100+ BP moves, and Trick is great for breaking stall, as well as neutering threats like CMCune, CurseTar, and DDMence.
The EVs let it outrun a max speed Jolly Gyarados after a Dragon Dance, maximum Special Attack, and rest in HP.

Latias@Leftovers
Levitate
4 Def/252 SpA/252 Spe
Timid Nature
Calm Mind
Dragon Pulse
Thunderbolt
Recover
My favorite set for my favorite pokemon. This is the only setup sweeper on my team, so this usually gets the cleanup in the end. It is the other glue on my team, checking threats like Salamence, Infernape, Suicune, Heatran, Empoleon, and Gyarados. It provides yet another Ground immunity to my team, as well as key resistances to Fire, Electric, and Water.
The set I chose for Latias was the Calm Mind version. It could take advantage of switch-outs, and was my favorite setup sweeper. Dragon Pulse is for the obvious STAB that lets me check Salamence, and Recover provides recovery. The last slot was a tossup between Surf, Thunderbolt, and Hidden Power Fire. Surf would let me check Heatran and Infernape better, but I do not need an SE move to do that. Hidden Power Fire would defeat Scizor and have better neutral coverage, though I would be helpless against the likes of Heatran and Suicune. Thunderbolt lets me check Gyarados, as I only have 1 check. A +1 Stone Edge from a Gyarados only averages 68%. Pursuit from Scizor does not OHKO, and a +1 Thunderbolt 2HKOs Scizor. Thus against any move besides U-turn, Scizor is at a disadvantage.

Scizor@Choice Band
Technician
248 HP/252 Atk/8 Spe
Adamant Nature
Bullet Punch
Pursuit
U-turn
Superpower
Scizor is the last member of my team, and a good one at that. It is the only physical attacker on my team, so it is the main answer to Blissey. It also handles Latias and Tyranitar, two things that would otherwise cause my team lots of grief. Also, my team is big setup bait for choiced moves, such as draco meteors from scarf latias, or shadow balls from choiced Rotoms, both of which are perfect pursuit bait. Being a Steel type, he takes some moves meant for Latias. Bullet Punch is STAB priority, serves as my check to Salamence, and revenge kills weakened threats. Pursuit lets me finish off the afforementioned threats. U-turn is another great STAB, and OHKOs Latias and lets me scout switches. It also does an insane % to Blissey. Superpower lets me manhandle Blissey, Tyranitar, and other Steels.
The EVs are simple, but the 8 EVs are in speed not defense. The speed lets me outrun other Scizor, U-turn does 30% and Rotom is often a great switch that lets me probably outrun their switchin if they U-turn, or resist the Superpower. Superpower does 67% on average with a minumin 63%, which is often enough to finish an opposing Scizor anyways. In a last poke vs last poke situation between Bullet Punches, the faster one wins as well. It also lets me outrun no speed vaporeon.
So that's the team. Yeah.
I've posted this team before, but there have been a few changes, and I didn't really get many replies the first time. If you like the team at least post "hey great team" or something. :p
