Hello Smogon! Here is my RMT!
I start with my Rarely Used Tech, Crustle. My core are 2 Sweepers and I dedicated 1 Support for each one of them. Finally, I complete my team with my belived Revenge Killer, Starmie.

Crustle
White Herb - Sturdy - Jolly (+Spe, -SpA)
252 Atk / 216 Spe / 40 SpD
Shell Smash - Stone Edge - X-Scissor - Earthquake
Here is my Rarely Used Tech. Since I have Magic Bounce I dont need to run Stealth Rock so I can use Crustle as a bluff of an entry hazard starter. Shell Smash is ridiculously overpowered when combined with White Herb and Sturdy. Most of the times he either takes something down before falling, seriously injures it or sweeps several pokemons (if not all) before fainting.
Thanks to Sturdy I will at last have a 1 HP pokemon with high Spe, Atk and 3 moves (2 of them been STAB), and there isnt much they can do to stop me. Also, if I manage to Shell Smash x2 I get a garanteed sweep unless they have a +1 priority user (The EV distribution allows Crustle to outspeed even Scarfed Jolteons).

Espeon
Light Clay - Magic Bounce - Timid (+Spe, -Atk)
252 Spe / 252 HP / 4 Def
Reflect - Light Screen - Yawn - Wish
Espeon's Job is to allow Cloyster to sweep. Magic Bounce also saves me from Stealth Rock which seriously hurts Ninjask-Dragonite, the fear of a switch in Espeon may be enoght for my opponent to avoid going for that.
The idea is to set up the Dual Screens. Then I can either Wish and Yawn. If I Yawn I inmediatelly switch into Cloyster. This way my opponent will have to either tank the sleep or switch. This is a very easy and effective way build up a potentially 6-0 Cloyster. If I drop the Screns and then Yawn before dying, I can switch into Cloyster and he will have a free Shell Smash, which means he is 1 Shell Smash away from a 6-0.
Wish is there if I want to Wish and then switch into Cloyster or Ninjask (if there is hazards on the board, to make Focus Slash alive). The heal can also help Cloyster when he wants to set up. HP EVs to maximise Wish's heal and obvious Spe EVs to allow Espeon to drop the Screen before they hit.

Cloyster
White Herb - Skill Link - Hasty (+Spe, -Def)
252 Spe / 252 Atk / 4 SpD
Shell Smash - Icicle Spear - Rock Blast - Hydro Pump
Cloyster is one of my two sweepers. Unlike Dragonite, he wont be stoped by Focus Sash, entry hazards and physical walls like Heatran, Skarmory, etc, nor he will be locked into Outrage.
Not much can be said about this since is a quite common build. STAB Icicle Spear is usually my main weapon. Rock Blast for when they resist Ice. Hydro Pump for when they have a lot of Def and low SpD (this takes adventage of the fact that is a STAB move and Shell Smash also gives +2 SpA).

Ninjask
Focus Sash - Speed Boost - Timid (+Spe, -Atk)
252 Spe / 148 Def / 108 SpD
Protect - Swords Dance - Baton Pass - Substitute
Here is my other support. Ninjask's job is to bulk up 3 Speed and 2 Atk, then Baton Pass into Dragonite who will then proceed to sweep.
The EVs are distributed to be able to reach max MS after the 1st Protect. 152 HP means I reach 301 HP been able to dodge 3x Sesmic Toss and 4x Substitute. The rest goes into defence to make a substitute who could potentially tank 2 attacks instead a single one.
Substitute is there in case I get Stealth Rock'd. I will go stack Speed with Protect and Substitute and then Baton Pass making any of my pokemons faster than the speed of light... surrender now or prepare to fight

Dragonite
Lum Berry - Multiscale - Adamant (+Atk, -SpA)
252 Atk / 164 Spe / 64 Def / 24 SpD / 4 HP
Outrage - Hidden Power [Fire] - Earthquake - Dragon Dance
The idea is to Baton Pass Ninjask once he reachs 3 Spe 2 Atk into Dragonite. Thanks to Lum Barry and Multiscale it is really dificult to stop him at that point. He will then decimate the opponent team with his STAB.
The reason why I choose Dragonite over other pokemon who would benefice from the +3 Spe +2 Atk is Multiscale. He is REALLY hard to 1HKO and that is the major flaw of this strategy if I where to choose anything like Haxorus, Salamance and others.
The reason of Lum Berry is not only to avoid their outs but to also remove the confusion from Outrage to allow the possibility of 6-0. Multiscale is also obvious to avoid 1HKO the turn I baton Pass him. With that EVs I will outspeed everything, even Choise Scarf Jolteon. After maxing his attack the rest goes into defence to avoid the said 1HKO inside Multiscale.
Outrage will most likely 1HKO everything that doesnt resist it (aka Steel) but Sturdy/Focus Sash users. Earthquake and Hidden Power [Fire] will 1HKO everything that can resist Outrage minus Air Baloon Heatran, so I really dont need any other move besides Dragon-type since its a wonderful 90 STAB move.
Dragon Dance is there for when I have to send him out without Ninjask support.

Starmie
Life Orb
Natural Cure
252 SpA / 252 Spe / 4 SpDf
Timid (+Spe, -Atk)
Surf - Thunderbolt - Ice Beam - Hidden Power [Fire]
Last but not least, a revenge killer. Not much can be said since is a very simple role. I used to have Rapid Spin in here but since I added Espeon to the team I rarely use it anymore, instead I have pretty much every type I need for a revenge kill and STAB Surf for the types I wont hit for Super Efective.
Suggestions are welcome!
