Just a new team now that I've returned to Pokemon after a long absence. A little standard in terms of Pokemon, but redeems itself (or so I think) in terms of sets, effort value spreads, and stuff. So far, it's done me very well.
Zapdos @ Leftovers
Ability: Pressure
EVs: 252 HP/180 Def/32 Spd/44 SDef
Bold nature (+Def, -Atk)
- Charge Beam
- Hidden Power [Ice]
- Roost
- Thunderbolt
This little guy right here has served me quite well. Zapdos is actually one of the first of my Pokemon to go, usually, but it typically does its job before it goes, which is to counter some fighters. It also has swept a team after it lost its special wall, and after a few boosts, it's nothing to take lightly. It hits pretty hard as it is and has valuable resists that go very well with the rest of the team.

Heatran (F) @ Leftovers
Ability: Flash Fire
EVs: 252 HP/136 SAtk/120 SDef
Modest nature (+SAtk, -Atk)
- Earth Power
- Lava Plume
- Rest
- Sleep Talk
I used to run a complete special wall variant of Heatran, with a Calm nature and 248 EVs in Special Defense. It did its job well. Little could break through it on the special defensive side. However, it lacked a certain kick to it. So, I split it up. It's still a strong sucker and can take a lot of hits, especially with RestTalk. My sleep absorber and status inducer. Most of what switches into Heatran is either a bulky water (which leads me into a good situation) or a very offensive threat that resists fire, such as Salamence, Garchomp, Gyarados, Tyranitar, or what have you. All of these hate being burned. A lot. Works very well in tandem with the other team members, as well.

Celebi @ Leftovers
Ability: Natural Cure
EVs: 252 HP/224 Def/32 Spd
Bold nature (+Def, -Atk)
- Grass Knot
- Leech Seed
- Recover
- Thunder Wave
Once again, an old soul I used many times. I always have to decide between six moves for Celebi. These four, Hidden Power [Ice], and Reflect. I felt pretty comfortable with dealing with dragons between Zapdos, Heatran's burns on switch-ins, and what have you, and I really wanted Celebi to have Thunder Wave. It came down to Leech Seed ... and I went with Leech Seed to really create a hazard for the opposing team. I still really want Hidden Power [Ice] on here, but I don't know where I'd put it. Thunder Wave CANNOT go, it's so invaluable. Staying in and taking hits from Gengar and Infernape to return a paralysis is so satisfying.

Tyranitar (F) @ Choice Band
Ability: Sand Stream
EVs: 252 HP/40 Atk/216 SDef
Careful nature (+SDef, -SAtk)
- Crunch
- Earthquake
- Pursuit
- Stone Edge
A specially defensive variant, you know the drill on this mother. A very reliable switch in against most special attackers, and always leaves a dent. My team gives it a lot of opportunities to switch in, as well, and I've done very well with him. The extra attack EVs help boost the attack some, and of course, sandstorm is awesome.

Vaporeon (F) @ Leftovers
Ability: Water Absorb
EVs: 188 HP/252 Def/12 SAtk/56 SDef
Bold nature (+Def, -Atk)
- Hidden Power [Electric]
- Protect
- Surf
- Wish
Vaporeon is the team's designated mother. She keeps everyone healthy, including an asleep Heatran, stealth rocked Zapdos, weak Celebi, injurred Tyranitar, or substituted-to-hell Garchomp. Also serves as a great Gyarados counter, but I guess I could switch over to Ice Beam to make me feel better about Celebi foregoing it. Slightly more specially defensive than most variations, as well, since I didn't need to hit any crazy mark to beat Garchomp.

Garchomp (F) @ Brightpowder
Ability: Sand Veil
EVs: 240 HP/16 Atk/216 Def/20 Spd/16 SDef
Impish nature (+Def, -SAtk)
- Dragon Claw
- Earthquake
- Substitute
- Swords Dance
If Garchomp does get banned, I'll have to change this. But, as of now, Garchomp actually serves as a VERY reliable defensive machine. It can take a lot of hits -- and obviously dodge a lot, too -- and the extra defensive reliability gives me enough time to make up for its attack. It loves opposing team burns and paralysis, much like Tyranitar, and is kept healthy by Vaporeon. Everyone hates this set, but it's effective, and for good reason.
