I love UU but I thought I would try making an OU team for once. I've also never done a RMT thread haha Let's see how this goes.
Swampert Torrent Relaxed
Leftovers
Earthquake
Ice Beam
Roar
Stealth Rock
252 HP / 4 Atk / 252 Def
This is obviously the standard Swampert Lead. The only Leads that would give me trouble would be Roserade or other Swampert. If Roserade appears I switch to Tentacruel to take the Sleep Powder and then switch to Scizor for the KO. For the opposing Swampert I switch to Rotom-C, who is also useful for switching in to an Explosion from Metagross, Heatran, or Bronzong also being common leads. I chose to run Roar over Surf and Protect for a few reasons. I need a phazer as certain Pokemon namely Calm Mind Jirachi and Curselax can set up easily on my Rotom-C, and it helps to shuffle the team through Stealth Rock. Surf seems to be a waste as I already have Tentacruel running it as well as Salamence with Hydro Pump.
Scizor Technician Adamant
Choice Band
U-Turn
Bullet Punch
Super Power
Pusuit
248 HP / 252 Atk / 8 Spe
This is Scizor doing what it does best. Scouting teams and revenge killing sweepers. Scizor benefits from Stealth Rock provided from Swampert, who also resists Scizor's fire weakness. If there is a Magnezone on the opposing team I will have hopefully found it by using U-Turn, In which Case I use Tyranitar to destroy it. Tyranitar also counters Heatran, Zapdos and Rotom forms, other common Scizor counters. Rotom-C counters Pokemon like Gyarados, Tyranitar, and Lucario that would set up on Scizor if he gets locked in to Pursuit
Salamence Intimidate Modest
Life Orb
Draco Meteor
Dragon Pulse
Hydro Pump
Flamethrower
4 Def / 252 SpA / 252 Spe
This set is rarely seen nowadays. I use this special based Slamence as a switch in for Tyranitar to sponge Ground, Fighting, Water, and Grass type attacks. Hydro Pump and Flamethrower provide great type coverage. Draco Meteor deals a lot of damage to well... anything. This set lures out Blissey in which case I switch to Scizor and KO with Super Power. Normally this set would run Choice Specs. But I chose Life Orb instead to avoid getting locked. With Scizor taking care of Starmie, and Latias, there is a chance of this Salamence performing a wonderful end game sweep.
Tyranitar Sand Stream Adamant
Choice Band
Stone Edge
Crunch
Pursuit
Earthquake
160 HP / 252 Atk / 96 Spe
Choice Band Tyranitar... Need more be said? Stone Edge and Crunch are the main attacks. Pursuit hurts Blissey pretty bad whether she switches or not. Tyranitar's role of knocking out opposing Ghost types make the feild a safer place for my own Rotom-C. As mentioned before, Salamence takes any super effective hit aimed at Tyranitar. As for the bulky fighting types, Rotom-C has no problem dealing with them using Will-O-Wisp.
Rotom-C Levitate Bold
Leftovers
Thunderbolt
Shadow Ball
Leaf Storm
Will-O-Wisp
252 HP / 72 Def / 96 SpA / 88Spe
Rotom-C plays the role of anti-Rapid Spinner for my team, as Scizor enjoys the Stealth Rock support. Leaf Storm will score a OHKO on enemy Swampert and deal great damage on opposing Tyranitar if I decide not to just burn it with Will-O-Wisp. Scizor and Tyranitar pick off the main counters to this set relatively easy. Gengar can be an issue if it's packing Hidden Power [Fire] or Focus Blast. Heatran switching in to my Will-O-Wisps will be countered by my Swampert, Tentacruel, or Salamence. And as mentioned before, Swampert's Roar deals with Pokemon that would set up on Rotom-C.
Tentacruel Liquid Ooze Calm
Black Sludge
Surf
Rapid Spin
Sleep Talk
Rest
252 HP / 56 Def / 200 SpD
This Sleep Talk Support set is great for taking sleep inducing moves, most notably from Roserade leads. Tentacruel can switch in on Fire, Fighting, and Ice. This is usually used to set up Toxic Spikes but I chose to run Rapid Spin instead. As many Pokemon have levitate or are Steel types so they seem like a waste to me.
