Just something I've been trying to put together. Comments greatly appreciated :)
Bronzong @ Macho Brace
Levitate
Sassy – 252 HP/ 86 Atk/ 80 Def/ 92 Sp. Def
-Trick
-Gyro Ball
-Earthquake
-Stealth Rock
Basically used to get Stealth Rock up, as well as support my strong (but somewhat slow) Life Orb-ers with a tricked Macho Brace. The Macho Brace also makes Bronzong's Gyro Ball very powerful, whilst not locking it in to an attack (like, say, a tricked Choice Band would).
Heatran @ Life Orb
Flash Fire
Timid – 252 Sp. Atk/ 4 Sp. Def/ 252 Spe
-Fire Blast
-Earth Power
-Hidden Power [Grass]
-Substitute
Ahh, Heatran. With Life Orb, it hits exceedingly hard, and this Heatran is meant for a late-game sweep. It is somewhat slow, however it is supported with both Bronzong and my Thunder Wavers. Substitute with Life Orb may whittle it's HP down alarmingly fast, however I do have the Wish support, and this is a fantastic move to use on the switch, allowing it to hit it's counter hard with an appropriate attack.
Celebi @ Life Orb
Natural Cure
Modest – 232 HP/ 240 Sp. Atk/ 36 Spe
-Thunder Wave
-Leaf Storm
-Hidden Power [Fire]
-Recover
My 'Tinkerbell'. It supports the team, and itself, with Thunder Wave, but at the same time threatens with a powerful, Life Orb STAB Leaf Storm. Hidden Power gets coverage, and Recover keeps it alive. Basically, it's supposed to support while remaining an offensive threat.
Vaporeon @ Leftovers
Water Absorb
Bold – 248 HP/ 224 Def/ 36 Sp. Def
-Wish
-Protect
-Scald
-Hidden Power [Electric]
Vaporeon provides Wish support that's much needed for my team, as well as checking some dangerous physical threats, like Excadrill and Gyarados. It also provides good general synergy with my team, resisting fire and ice attacks aimed at Celebi as well as water attacks aimed at Heatran.
Dragonite @ Leftovers
Multi Scale
Impish – 252 HP/ 52 Atk/ 204 Spe
-Dragon Dance
-Dragon Claw
-Fire Punch
-Roost
Dragonite is meant for an outright sweep, as a bulky Dragon Dancer. It appreciates T-wave support (allowing it to Roost before the opponent, if it doesn't have a DD up) as well as SR support from Bronzong, allowing it to get some KO's it mightn't otherwise get. I've gone with Impish to emphasise bulk, and get the best chance of Dragon Dancing up.
Blissey @ Leftovers
Natural Cure
Bold – 252 HP/ 252 Def/ 4 Sp. Def
-Seismic Toss
-Softboiled
-Thunder Wave
-Aromatherapy
Blissey seems like a bit of an after-thought, but it actually does several important things for my team. Firstly, Along with Celebi, it provides Thunder Wave Support. Secondly, it carries Aromatherapy to heal off status that could cripple my team (Burn on Dragonite, Toxic on Vaporeon, Paralysis on Heatran). Finally, it provides excellent Special Defense, and can take special hits much better than Vaporeon and Bronzong, thus walling a lot of threats.
Well, there it is. Hope it isn't (entirely) awful, but I'd reallt appreciate anything you have to offer. In particular, I know that this team has trouble with Reuniclus (though, if I could get it before it starts boosting with Calm Mind, then Celebi/ Heatran could hit it hard...)
Mmph. Anyway, thanks heaps!
