So... I kinda gave up on my previous team 'cause I have no clue what to do with it right now and have decided to move on to a new team. It seems to do pretty decently, but I think it might be weak to something and could use some help with one of it's members. Anyways...
Gardevoir (F) @ Choice Scarf
Ability: Trace
EVs: 150 HP/252 Spd/108 SAtk
Modest nature (+SAtk, -Atk)
- Energy Ball
- Psychic
- Trick
- Shadow Ball
Alright, I'm gonna be perfectly honest about Gardevoir, I thought up her set while talking to a friend of mine, thought she could make an interesting lead, and winged her EVs. Anyways, the set and item should be fairly straight forward. Energy Ball kills leads like Omastar and Kabutops unless they run a sash, shadow ball 2 hit KOs Zam while putting a small dent into Uxie and the like, Psychic is for reliable stab, and Trick is to deal with anything that my other moves couldn't deal with. Choice scarf allows her to out run every lead out there, unless it's a faster scarfer or is Electrode. The EVs are meant to make her fairly bulky while still being able to hit hard, but if you think there's a better EV spread for her, then please tell me!
Edit: Despite completely winging them, It doesn't seem like I did to bad on the EVs. I just recently found out that Synchronize doesn't pass sleep onto stuff so I'm now wondering if Trace would actually be a good idea on her since it could potentially be useful mid/late game.
Edit 2: Ability has been changed to Trace for it's potential usefulness in the mid/late game.

Aggron (M) @ Choice Band
Ability: Rock Head
EVs: 252 Atk/6 Def/252 Spd
Jolly nature (+Spd, -SAtk)
- Head Smash
- Aqua Tail
- Ice Punch
- Low Kick
Hitmonlee didn't test well, so at the suggestion of Flameheart, has been replaced with Aggron for the time being. Not only can Aggron switch in on more, but STAB Head Smash is a little more difficult to switch into than STAB Close Combat, unless it misses. Jolly was selected over Adament to allow him to outrun as much as possible. Over all, I'm pretty happy with him. Head Smash really does rip into most walls like their nothing, so thanks Flameheart!

Manectric (M) @ Choice Specs
Ability: Static
EVs: 6 HP/252 Spd/252 SAtk
Timid nature (+Spd, -Atk)
- Flamethrower
- Switcheroo
- Thunderbolt
- Hidden Power [Grass]
I've been wanting to test a Manectric for awhile now, and I gotta say, he's pretty cool. Switcheroo deals with mono attackers and stuff that seem to piss me off to no end and everything else is for coverage. I'm wondering if I could maybe use a different Hidden Power type since Gardevoir carries Energy Ball. Flamethrower was selected over Overheat so that I could keep him in longer if need be.

Regirock @ Leftovers
Ability: Clear Body
EVs: 252 HP/36 Atk/222 SDef
Careful nature (+SDef, -SAtk)
- Earthquake
- Stealth Rock
- Stone Edge
- Toxic
Like any team, I needed a Stealth Rocker at this point. I selected Regirock over Registeel since he can hit harder and has better stab. Thunder Wave was picked over Explosion to slow certain threats down when Gardevoir has lost it's scarf or I'm unable to set up with Torterra. I'm thinking Toxic might be better here, though.
Edit: Thunder Wave wasn't doing much for me, so it has been changed to Toxic to allow it to wear down certain threats that could get on my nerves if their fate hasn't been sealed.

Altaria (F) @ Leftovers
Ability: Natural Cure
EVs: 252 HP/18 Atk/64 Spd/176 SDef
Careful nature (+SDef, -SAtk)
- Dragon Dance
- Dragon Claw
- Roost
- Heal Bell
As sad as it is for me to say this, Torterra just wasn't doing enough for the team. I needed to find someone that could switch in on fighting and ground attacks and do something outside of simply taking a hit for the team. I eventually decided on Altaria's defensive dragon dance set which could switch in on a number of attacks and at the very least remove status from the team. She can even eventually set up her own sweep from time to time which is always fun. Being weak to Ice isn't quite as damning for her as it was for Torterra either and could switch in on Venasaur and not get KO'd by Sludge Bomb which is something that Torterra couldn't do.

Weezing (M) @ Leftovers
Ability: Levitate
EVs: 252 HP/18 Spd/240 SDef
Bold nature (+Def, -Atk)
- Rest
- Sleep Talk
- Sludge Bomb
- Will-o-wisp
RestTalk Milotic's a very cool, bulky pokémon that can be incredibly annoying to take down. However, though I didn't feel the effects of having two pokémon weak to fighting type moves in the beginning, it didn't take to long before I started to. I had hoped that Altaria would help patch it up, but she just wasn't enough. I had originally decided to test Calm Mind Slowbro since it seemed like a really fun set. However, His set was incredibly easy to stop and he just didn't work well with the team as a whole. I began looking through all the possible pokémon that could patch up all of my problems. The only pokémon that really seemed to fit was Weezing who can not only take the fighting and ground attacks aimed at Aggron/Manectric/Regirock, but he also checks Venasaur. I'm a bit worried that getting rid of a Bulky water leaves me with very little to do against fire types, especially Houndoom. You have no idea how worried I am that I'll end up hitting Will-O-Wisp with sleep talk as a Houndoom switches in, or Arcanine. But what're you going to do?
And that's the team.
