I had what was probably one of the most amazing battles I've had in a while with Trachy using this team, but I'd still like to see what I can improve, and of course he beat me to posting :P

Rotom-H @ Choice Specs
Ability: Levitate
EVs: 64 Def / 252 SpA / 64 SpD / 128 Spe
Timid Nature
- Volt Switch
- Trick
- Overheat
- Hidden Power [Ice]
Well, welcome to what I use for every Rotom-(Letter). Except Rotom-W.
Just kidding, but the EV spread works amazingly, pulling off as my Bulky Sweeper.
Choice Specs packs a punch, considering most think it's a Scarf. That 252 EVs Choice Speced Volt Switch is gonna hurt quite a bit more than expected. He breaks up Scarfodile (Krookodile with Choice Scarf), as they are locked into an Earthquake. It can hit anything super hard with Overheat. It has Volt Switch to leave the fight for something else to pick up, while Trick can screw over physical sweepers with Scarves, or Lefties, or Sashes. HP Ice provides amazing coverage for it. Gotta love him.

Froslass (F) @ Focus Sash
Ability: Cursed Body
EVs: 4 HP / 252 SpA / 252 Spe
Modest Nature
- Thunder Wave
- Destiny Bond
- Hex
- Ice Beam
My mischievous sweeper. The EVs are classic sweeper style, with a little bit of HP just because it's what was there. Modest Nature provides a Special Attack boost, considering Froslass has some pretty awesome Speed already. Cursed Body comes in handy if you switch into anything scarfed, because that's an auto forced switch.
Thunder Wave is the greatest support for Frosty, because it can slow down most anything that's faster than it (Ice Beam can take down Ground types, which can't be paralyzed), then you can either use Destiny Bond or you can use one of your coverage moves (Hex and Ice Beam are STAB, but you know..) and then hope you can outspeed whatever comes in to finish you off. Great for taking down those seemingly impossible to finish off sweepers.

Krookodile (M) @ Choice Scarf
Ability: Moxie
EVs: 4 HP / 252 Atk / 252 Spe
Adamant Nature
- Crunch
- Earthquake
- Stone Edge
- Outrage
My Choice Scarfed Krookodile. I'm heavily considering taking 128 EVs away from Speed and throwing it into either one of his defenses (That's a bit sneaky, ya know?), or straight up into his HP stat. Just a thought, I'd like to see comments on that. Anyway, onto his stuff. Adamant is better than Jolly when Scarfing if you already have a nice enough base Speed, and I'm really not worrying about outspeeding other Krooks (128 in Defense would help that..). Crunch is my STAB, you don't have to worry about Levitate Psychic types (It can be great to take those out if your opponent is predicting an Earthquake) and has a chance to lower Defense. Earthquake is a total powerhouse move, but it gets walled out by Levitate and Flying types. Stone Edge is coverage against Ice and Flying mainly, but it takes down others as well. Outrage is something that hits most Pokemon for neutral damage, as UU doesn't have many Steel types, so that's always a nice choice for neutral hits.

Suicune @ Leftovers
Ability: Pressure
EVs: 240 HP / 76 Def / 4 SpA / 188 SpD
Relaxed Nature
- Aqua Ring
- Protect
- Toxic
- Hydro Pump
This guy is what made me like Aqua Ring more than Recover. His defenses are equal at 313 each and his HP reaches exactly 401. (Takes 5 Seismic Tosses from Chansey)
Aqua Ring gives him a double healing boost, while he can use Protect to stall it out, which if I recall he gets about 50 HP back every turn. This means you can stall back around 100 HP with 2 Protects, and you can use it to support Toxic. Toxic is there as his main damaging function, which seems sad, but really works well with his gradual recovery skills. Hydro Pump is STAB, and he really needs the power over accuracy, which is why I didn't go with Surf.

Mienshao (M) @Focus Sash
Ability: Regenerator
EVs: 4 HP / 252 Atk / 252 Spe
Jolly Nature
- Swords Dance
- Drain Punch
- Stone Edge
- U-turn
Classic sweeping EVs, no bulk needed for this frail little guy. He can abuse that little Focus Sash of his by getting Wishes from Chansey, and Regenerator boosts. With Drain Punch too! Jolly nature is for Speed.
Swords Dance is my little touch, I don't really see it a lot on Mienshao to be honest. (Is it just me?) Drain Punch is STAB that doesn't take 50% of your health away if you use it at the wrong time. Instead, it actually heals you when you use it! :D - Stone Edge makes for great coverage for any Fighting type. U-turn can follow through with his hit and run play, and lets him switching out after a Swords Dance not that bad, which doing twice the damage he would have before and all. My physical sweeper.

Chansey @ Eviolite
Ability: Natural Cure
EVs: 252 HP / 252 SpD / 4 Spe
Calm Nature
- Heal Bell
- Wish
- Toxic
- Seismic Toss
I didn't get complicated with the EVs. 252 in his Special bulk. The 4 Speed lets him take on Chanseys who think they're cool with their 4 Defense EVss :P (To all who actually do do that.)
Wish is a great 352 HP boost to give to anyone on my team, and it supports Chansey for some nice healing, if she can you know.. survive for it. Heal Bell gives support to anything that inflicts status to my team, and to Chansey herself. Toxic is of course my Chansey's main way of damaging, while Seismic Toss is viable for after using Toxic. Keeps the whole team going, I like Chansey's role in my team.
