So after a few months and a lot of testing on the shoddy latter and on wifi I've created what is by far my most successful standard team (currently using more on the Suspect ladder). However it still has a few weaknesses that I'm hoping to address.

Ability: Natural Cure
Starmie is a straight up fantastic lead. It absolutely destroys a huge portion of leads with it's disgustingly powerful STAB Life Orb Hydro Pump. It's great speed let's it outrun or tie with just about every common lead except Aerodactyl, Ninjask, and Choice Scarf leads. But one of the shining attributes of this set is without a doubt Rapid Spin. After I get down most leads to their sash, I can simply spin away whatever entry hazards they tried to set up and KO them in return. I can and also frequently do save Starmie for later on in the match so she can come back to wreak havoc again on a weakened team, or spin away some hazards that ended up being set up later. Definitely my favorite lead in OU at the moment.

Ability: Clear Body
Lum Berry Metagross is fantastic for quite a few reasons. It's incredibly bulky, can take status, dish out monstrously powerful hits, and set up stealth rock, while also being able to explode to take out a threat, such as Crocune or Curselax. Metagross is also my lead Starmie's main partner in crime as he can come in on a few of the leads that Starmie really hates to go up against, like Tyranitar and Machamp.

Choice Scarf Flygon is quite possibly the best scout in the entire game. It out-speeds just about everything allowing me to either smack it with the appropriate attack, or U-Turn safely if I predict a switch. Also can do a lot of damage to an already weakened team once I know what they have. And of course I partnered him with his favorite teammate and the most overused pokemon in standard...

Seriously, what am I supposed to say about Choice Band Scizor? Everyone who plays OU should have encountered this beast at least once. STAB Technician Bullet Punch absolutely tears through anything that isn't massively invested in Defense and HP or Resists it. STAB U-Turn allows for incredibly hard hitting scouting. Pursuit locks non-substitute/protect HP Fire Gengars and pokemon like him who share a Pursuit weakness. And Superpower, of course, is for murdering the pink obese nurse whore, Blissey, who is my second least favorite pokemon in OU, after Breloom. Also covers both of Flygon's weaknesses while Flygon resists Scizor's.
252 Atk 252 Spe 6 HP
Dragon Dance Life Orb Gyarados is an absolute monster after he sets up and is easily capable of running through teams. With excellent typing, great defenses in 95/79/100, and Intimidate, Gyarados can switch in on a hell of a lot of things, except powerful rock and electric attacks, who will make short work of him if I'm not careful. And it is because of this extra natural bulk that I chose him over his more widely used cousin, Salamence, for the role of set-up sweeper. And obviously, choosing Gyarados lets me use this team on the Suspect ladder, where Salamence is forbidden.

Hidden Power (Ice)
My final pokemon and my main Wall Breaker for taking down stall team, while also being able to take down a ton of OU's top offensive threats in the process. The moves Infernape has allow him to hit every pokemon for at least neutral damage, and a huge number for powerful super effective damage. The main reason why I chose Infernape is because he can easily pound the ever-loving crap out of Skarmory and Blissey, two pokemon that can give my team a lot of problems if I let them stick around.
