Team Overview






You'll see that I don't rely on walls, more on attack power and speed. I also put together a team that can switch in on different attacks and absorb them (Kingdra, Metagross, and Latias especially).
Lead

Adamant @ Focus Sash
Ability: Oblivious
4 HP 252 Atk 252 Spd
-Stealth Rock
-Endeavor
-Earthquake
-Ice Shard
My trusty Mamoswine. He has been a fantastic lead for me. Stealth Rock first if the opponent's lead is going to setup as well. Then, depending on the lead, I can either Ice Shard for Aerodactyl (2HKO), Earthquake most other leads, Endeavor if the other lead is faster and brings me down to my Focus Sash, then Ice Shard to sweep them away, or I can switch out to another pokemon. The reason this works is because nobody suspects my Mamoswine to be faster than their lead.
Physical Sweepers

Naive @ Life Orb
Ability: Blaze
4 HP 252 Atk 252 Spd
-HP Ice
-Vacuum Wave
-Fire Blast
-Close Combat
Again nobody suspects this moveset. I've heard before that Stealth Rock/Spikes ruin my Focus Sash but that doesn't worry me. Early in the battle, I use priority moves to sweep away unsuspecting pokemon with Mamoswine, Infernape, and Metagross. This has worked spectacularly for me. Also, I can still Endeavor after a Flare Blitz or two.
Edit: Maybe this new combination would work better against my Steel problems.

Impish @ Leftovers
Ability: Clear Body
112 HP 252 Atk 12 Def 132 Spd
-Rock Polish
-Meteor Mash
-Earthquake
-Explosion
A great switch-in to any physical sweeper w/o Earthquake, but even then still great. Again, I use a priority move. Earthquake is for other steels and Zen Headbutt is just a good STAB. Psych Up is for switching in on a Scizor, Gyrados, or Salamence and getting their +Atk and/or +Spd. Rock Polish is also a good move if I want to get ahead of my opponents. But I don't find it necessary since I use a strong STAB priority move.
Special Sweepers

Timid @ Life Orb
Ability: Levitate
252 Spd 252 SpAtk 4 SpDef
-Recover
-Draco Meteor
-Dragon Pulse
-Surf
This hasn't been my favorite sweeper. Honestly, it's been a real let down. I expected it to win me as many battles as the other pokemon on my team, but it hasn't. But, it has been a great switch-in to just about any special attack. I can get in a Calm Mind or two and then sweep, but a good Blissey puts a stop to that. If someone suggest a better moveset/pokemon that fits the idea here then I'd be really happy.
Edit: Instead of Calm Mind, maybe switch around the EVs to power up Latias's SpAtk more and then rape with a STAB Draco Meteor?

Timid @ Choice Specs
Ability: Synchronize
252 Spd 252 SpAtk 4 SpDef
-HP Fire
-Shadow Ball
-Focus Blast
-Trick
Hands down my favorite revenge killer. Its the fastest specs user I know of that pulls this off effectively. I was thinking Choice Scarf when I saw the monstrous 552 SpAtk Stat and the 371 Spd Stat. The speed gets it past even max Spd Latias (but nobody suspects it to OHKO/2HKO with Shadow Ball).
Late Game Sweeper

Jolly @ Life Orb
Ability: Sniper
4 HP 252 Atk 252 Spd
-Substitute
-Dragon Dance
-Outrage
-Waterfall
After I've seen enough of my opponent's team, I send in Kingdra. Nothing stands in his way (except maybe Skarmory or Bronzong). I love sending in this beast to a pokemon that gets scared and runs away to a Toxic/Thunder Wave user. I just Substitute and Dragon Dance while my opponent tries to get through the Substitute. I can get in one or two Dragon Dances usually. Then rip through their team with Outrage or Waterfall.
I hope you enjoyed my team. This has been my first made OU team. It has gotten me a very respectful rating in my eyes and I hope you like my idea of surprise too.
Changes are in BOLD
