Hello, users of Smogon. This is my first attempt at a RMT, so hopefully all goes well. If any rules are broken, please tell me and I'll do my best to make everything right.
I basically came up with a team that could do a bit of everything, save for Baton Passing since I'm not a huge fan of it. So after a little experimenting, this is what I came up with. Don't hold back on suggestions. I want to hear what you have to say :)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Crobat @ Leftovers
Ability: Inner Focus
EV Spread: 252 Speed, 252 Attack, 4 HP
Nature: Jolly
Taunt
Brave Bird
Roost
U-Turn
Odd, I know, but follow me on this one. LeadApe’s Fake Out is virtually worthless and it stands no chance against Brave Bird. Taunt is great for those Leads hoping to lay out Stealth Rock/Spikes/Toxic Spikes. This guy infuriates Roserade since he resists both STAB attacks, keeps it from laying out entry hazards like Toxic Spikes and has a SE STAB attack. He outspeeds and OHKO’s Scpetile as well, who has proven to be somewhat of a hassle in the past. Roost lets Crobat take away some of that Brave Bird recoil and gets rid of some weaknesses. U-Turn gets him out of a bad situation while still doing a bit of damage on the way out.

Gengar @ Life Orb
Ability: Levitate
EV Spread: 252 Special Attack, 252 Speed, 4 HP
Nature: Timid
Shadow Ball
Energy Ball/Thunderbolt
Psychic
Focus Blast
I usually save him for the halfway point of the game, usually after Hippowdon, and let him decimate everything in sight while trying to not get touched by of my opponent’s attacks. Umbreon has a bad habit of attracting Machamp’s Dynamicpunch and Infernape’s Close Combat, so Gengar comes into to absorb the moves. Exploders hate seeing me switch to Gengar. Being immune to Rapid Spin is another huge plus for him and he counters the famous Spinners well. Max Special Attack + Life Orb Starmie’s Surf fails to OHKO while Shadow Ball is a OHKO to that annoyance. Energy Ball is a OHKO on Donphan thanks to SR damage, and the chance is high even without it while Swampert stands no chance. Thunderbolt rids me of any problems with Gyarados and Skarmory, and possibly Starmie after entry damage. Psychic is wonderful for switching into Infernape as Gengar outspeeds it and delivers the pain. Focus Blast offers great coverage and takes care of T-Tar and Heatran.

Hippowdon @ Leftovers
Ability: Sand Stream
EV Spread: 252 HP, 168 Defense, 88 Special Defense
Nature: Impish
Stealth Rock
Slack Off
Earthquake
Crunch/Stone Edge/Roar
My best Physical Wall, and a personal favorite Pokemon of mine. He is also my Stealth Rock Pokemon. Slack Off/Lefties keep him alive and Earthquake is the powerful STAB move. Crunch helps against other sturdy Pokemon that Earthquake doesn’t do a whole lot to and few Pokemon enjoy a Defense drop. Stone Edge hits the Flying types and provides good coverage with Earthquake. Roar is another option but it honestly doesn’t get a lot of usage. Hippo usually appears early for SR and to counter an Electric attack thrown at Crobat.
I’m considering Skarmory to avoid the Sand should it be seen as too detrimental to the team. On the downside, it would make my team would be a bit too weak to Electric and take away the ground counter for them. Another candidate I'm considering is Celebi. Heal Bell could help should a Thunder Wave hit Umbreon or Scizor. A Screening variation would benefit the team nicely as well since the threat of priority moves is almost nullified and could help the Life Orbers should they ever lose the Speed contest.

Umbreon @ Leftovers
Ability: Synchronize
EV spread: 252 HP, 92 Defense, 164 Special Defense
Nature: Careful
Wish
Payback
Protect
Toxic
Wish support is fantastic to have for this team since there is a great deal of switching on my part, and Umbreon provides Wish support very well. He is more Special Defense based because I need someone who can take a bit of damage from the Special Attackers. Wish is great for healing Pokemon like Gengar or even Umbreon when Protect is used right after it. Protect lets me scout for Choice Users and works real well if it is a Normal, Fighting or Ground move because Gengar loves those moves. Toxic is wonderful for bringing down an annoying Wall and Protect on top of it makes for a hair-ripping moment. Payback is cool for hitting opposing Gengar and Taunters hoping Umbreon doesn’t have an attack.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Scizor @ Choice Band
Ability: Technitian
EV Spread: 252 Attack, 252 HP, 4 Speed
Nature: Adamant
Bullet Punch
U-Turn
Superpower
Pursuit
Well, he’s my favorite Pokemon besides Mewtwo and he has proven to be a real force wherever he goes. His immunity to Poison has helped me out quite a bit in the past against Toxic lovers and he does a wonderful job of heavily damaging or killing fleeing Pokemon. U-turn lets me bail Scizor out of there while doing some damage. Superpower is nice because it takes care of any Magnezone hoping to trap me (would work well for Skarmory should I use him) and destroys non-Scarfed Heatran. Scizor is usually late game cleanup or will make an appearance to absorb a Toxic early if that situation happens.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Infernape @ Life Orb
Ability: Blaze
EV Spread: 64 Attack, 252 Special Attack, 192 Speed
Nature: Naïve
Grass Knot
Fire Blast
Close Combat
Hidden Power Ice
Man, I love this guy. With these moves, Infernape can hit every Pokemon for at least Neutral damage, which is very handy. Grass Knot lets him laugh at Swampert. Fire Blast decimates Steels like Skarmory and takes out the popular Scizor, though Bullet Punch can present a threat but I’m not sure how much it would do. Close Combat is a mighty STAB Attack as well, allowing Ape to dish out heavy on the Physical side. Blissey is no problem. HP Ice takes care of the Dragons.
