I thought up this team as fast as a typed it up. And as you can see, I didn't really spend much time typing it up, so I'd appreciate your suggestions.
Metagross @ Lum Berry
Adamant / Clear Body
200 HP / 236 Atk / 12 Def / 44 SDef / 16 Spd
~ Stealth Rock
~ Meteor Mash
~ Bullet Punch
~ Earthquake
This is the best lead ever, IMO. Bulky enough to take ever super-effective hits, reliable in setting up SR, and possesses anti-lead capabilities with Bullet Punch. I don't like using Explosion as I've already got Heatran for that job. People often think I don't have EQ on the set too, and I use this to my advantage. 44 SDef EVs give Metagross a bit more Special Defensive bulk to take Draco Meteors and assorted neutral special attacks. Lum Berry ensures that I beat Lead Roserade and Smeargle as an EQ + Bullet Punch knocks both of them out.
Heatran @ Choice Scarf
Naive / Flash Fire
56 HP / 252 SAtk / 200 Spd
~ Fire Blast
~ Earth Power
~ Explosion
~ Hidden Power (Grass)
Awesome when paired up with Metagross. Switches into Will-o-wisp's aimed at Machamp as well. Pretty self explanatory. Gives me security against Lucario and Infernape as generally neither is Scarfed. 200 Spd is enough to outspeed Jolteon and other positive base 130s, and that will suffice for me. Hidden Power Grass isn't necessary on the set as Latias owns pert's ass, so I was thinking maybe replacing it with Dragon Pulse or HP Ice (but Dragons are generally covered by P-2 anyways).
Latias @ Life Orb
Timid / Levitate
4 HP / 252 SAtk / 252 Spd
~ Draco Meteor
~ Grass Knot
~ Hidden Power (Fire)
~ Recover
I love this set. The only problem is that I'm walled by Heatran, which does pose to be a bit problematic. Draco Meteor for the sheer power, capable of OHKO'ing a lot of things that don't resist it once they take residual damage. Grass Knot is especially for Swampert, who otherwise gives Zapdos (the star of the show) a hard time. HP Fire is for Forretress and the ubiquitous SCIZOR.
Porygon2 @ Leftovers
Bold / Trace
252 HP / 216 Def / 40 SAtk
~ Ice Beam
~ Thunderbolt
~ Toxic
~ Recover
So I was looking for something to counter DD beasts like Mence and Gyarados. I went through things like Swampert (with Stone Edge) and Vaporeon (with HP Electric), but decided that P-2 was the best duck for the job. Toxic > Thunder Wave to allow me to win stallwars.
Machamp @ Leftovers
Adamant / No Guard
252 HP / 252 Atk / 4 Spd
~ DynamicPunch
~ Payback
~ Rest
~ Sleep Talk
Three of the biggest problems for Zapdos are Blissey, Snorlax, and Tyranitar. Machamp is capable of dealing with all three of these pests. Payback is for Ghost types who switch in predicting a Fighting attack, and RestTalk for the status absorption and overall increase in bulkiness.
Zapdos @ Leftovers
Timid / Pressure
192 HP / 136 SAtk / 180 Spd
~ Thunderbolt
~ Heat Wave
~ Hidden Power (Ice)
~ Roost
Yep, it's an offensively-based defensive Zapdos. I know from experience that Zapdos is extremely difficult to take down, so if one removes all of the pokémon that are able to do so from the game, then Zapdos essentially sweeps entire teams. HP Ice for Flygon and Gliscor, two annoying pokes that ruin fun, and Heat Wave is for Steels, and Celebi. 180 Spd EVs puts me at 309 Speed, enough to outrun max speed Lucario, as well as the pokes that try to outspeed it by one or two points, such as Gliscor.
