Merciless Dragons

In battles, my old team didn't fare well against most Ice Pokemon, nor did it have very high defenses or speed, and was often Out-sped and otherwise OHKO'd.
Three Pokemon on that team, however, fared pretty well against others and offered great offense, defense, and support. Those Pokemon were Kingdra, Breloom, and Skarmory. Kingdra, in rain dance, swept the floor with nothing but a flick of it's nose, so to speak. The only problem I had were other dragon attacks, and a Max Special Attack Porygon-Z with Tri Attack. Breloom, using a Spore Punch combo, swept the floor with Slaking, among other Pokemon who Focus Punch hits hard on. Along with Seed Bomb for STAB, bringing down Water Types, and Stone Edge, for nasty flying types who pose a great threat against Breloom, Breloom proved to be an excellent and very important addition to my team. The Third Pokemon was Skarmory. Using a Torment/Roar Stealth Rock Combo, it provided amazing support for my team. Stealth Rock gave me some OHKO's I was unable to get without it. Roar helped me scout through my opponents team, while dealing damage without lifting a finger. Torment, for when I was stuck on a Pokemon I could beat down with Steel Wing, annoyed the opponent, while making my sweep easier.
With those three Pokemon in mind, I have chosen to add two of them to my new team. Skarmory was important, and he will be used from time to time in lieu of another Pokemon, but not as the main Pokemon for this team.
This team is centered around two Pokemon: Salamence, and Kingdra.
We all know Salamence as one of the best sweepers OU can offer, because of it's great stats and typing. As such, Kingdra is another great addition to this team, because of it's resistances, power, speed in the rain, and it's only weakness, Dragon.
Let's go over these Pokemon. Things will become more clear in a little bit.


Salamence @ Life Orb
Adamant Nature | 252 Atk / 252 Speed / 4 HP
-Dragon Dance
-Dragon Rush
-Earthquake
-Roost

Dragon Dance is a must, as it raises Salamence's two best stats. I prefer Dragon Rush over Outrage and Dragon claw, being as it has a power of 100 and a 20% Flinch ratio. (I don't understand why Smogon doesn't recommend this in a physical set, it's a lot better than Dragon Claw, and Outrage locks you in, AND confuses you...) Earthquake takes care of grounded steels, mainly Heatran and Metagross, and Roost is used to recover battle damage and life orb damage.


Kingdra @ Life orb
Naughty Natured | 252 Attack / 240 Special Attack / 16 Speed | Swift Swim
-Draco Meteor
-Waterfall
-Hydro Pump
-Rain Dance

Well, Rain Dance is an obvious choice for this set, seeing that it has Swift Swim. Waterfall being it's main STAB Attack, it does incredible damage against Pokemon who don't resist it. Hydro Pump is for Physically Defensive Pokemon, and Draco Meteor provides exceptional STAB against other Dragons. This set is used to sweep, and boy, does it sweep.


Breloom @ Toxic Orb
Adamant Natured | 48 HP / 252 Attack / 208 Speed | Poison Heal
-Spore
-Focus Punch
-Seed Bomb
-Stone Edge

This set utilizes Brelooms amazing attack stat, and it's ability to re-gain 1/8 of it's health each turn by being Poisoned. It is also Brelooms trademark moveset. This set uses Spore and Focus Punch to rid myself of Empoleon, which can pose a threat to Kingdra. It also uses Seed bomb to get rid of Milotic, Vaporeon and Suicune, while using Stone Edge to destroy Ludicolo, which all can, in the long run, destroy Kingdra.


Kabutops @ Damp Rock
Adamant Natured | 72 HP / 252 Attack / 184 Speed | Swift Swim
-Rain Dance
-Aqua Tail
-X-Scissor
-Stealth Rock

Kabutops can set up Rain Dance, or benefit from Kingdras Rain Dance, with Swift swim, plus an extra boost for Aqua Tail. Using a damp rock, Rain Dance is granted 3 extra turns, which can come in handy in case Kabutops faints, giving Kingdra the benefit of Rain Dance and not having to set it up. X-Scissor gives me great type coverage, while Stealth Rock grants me OHKO's I could not achieve otherwise. Aqua Tail is a threat to the opponent, with STAB, heavy investment in Attack, and Rain Dance, if up.


Magnezone @ Leftovers
Timid Natured | 40 HP / 252 Special Attack / 216 Speed | Magnet Pull
-Substitute [Subject to Change]
-Thunderbolt
-Hidden Power Ground
-Magnet Rise

This Magnezone is purely for destroying Steel types that could become a problem for my Salamence, mainly Skarmory. Substitute prevents the Steel Pokemon from hurting me, so that I can effectively dispose of it. Thunderbolt is there for Skarmory, where Hidden Power is there for every other steel type Pokemon. (Again, I don't know why Smogon recommends Grass or Fire Hidden Power in this set, fire doesn't do much against Heatran, and Ground 2x's or 4x's just about all other Steel types except Skarmory.) Magnet Rise prevents Earthquake from supereffecting me, so that it can easily stay in the battle.


Starmie @ Leftovers
Timid Natured. | 136 HP / 156 Defense / 216 Speed | Natural Cure
-Rapid Spin
-Ice Beam
-Thunderbolt
-Recover

This Starmie covers both of my Dragons by ridding them of entry hazards that could cripple them, mainly Salamence. It also uses Ice Beam to get rid of opposing (And faster) Dragons. Ice beam and Thunderbolt are there to cripple any foe for early Rapid Spinning, and Recover is used, with a high speed stat, to recover health before any more health is lost.
