I just wanted to unveil my team, hoping that the great community of Smogon could help me out. I'll try to give out as many details as possible.
-=Dark Fusion=-
Azelf @ Focus Sash
Naive Nature
6 Atk / 252 Sp Atk / 252 Speed
-Taunt
-Stealth Rock
-Psychic
-Explosion
Max Speed is needed to at least tie with Positive Natured Speed 115s. It allows me to set-up Stealth Rock and disable slower leads with Taunt that usually set-up. Psychic for STAB and the ability to OHKO a lot of leads and Pokemon. Explosion for it to go out with a bang, having the ability to OHKO the likes of Blissey and Gyarados (if BulkyDos, Stealth Rock damage is needed after the Intimidate; the same goes for Blissey if I have a -1 Atk).

Celebi @ Leftovers
Bold Nature
252 HP / 220 Def / 36 Speed
-Leech Seed
-Reflect
-Recover
-Grass Knot
Physical Wall and Gyrados/Lucario Counter. Reflect stops most physical sweepers and allows me to support the team. Leech Seed obviously causes switches as well as drain the foe's HP while replenishing my own. Recover is to keep Celebi out longer, obviously and Grass Knot for STAB (It also does quite a number on quite a few Pokemon in OU).
Heatran @ Leftovers
Modest Nature
252 HP / 48 Def / 208 SDef (EV Spread suggested by Venom to maximize Sp Def resistance)
-Lava Plume
-Earth Power/Dragon Pulse
-Rest
-Sleep Talk
Celebi + Heatran are obviously an amazing pair. RestTran allows me to take advantage of those resistances and gives me an awesome wall. Heatran is my status sponge, as well as gives me a semi-support move with Lava Plume's burn rate. I'm still not sure on whether to go for Earth Power or Dragon Pulse, though.
Swampert @ Leftovers
Impish Nature
252 HP / 6 Atk / 252 Def
-Waterfall
-Earthquake
-Avalanche
-Roar
The Swampert was suggested by Venom to handle threats such as Weavile and Scarftran. Water/Ground/Ice will let it hit next to everything commonly found in OU (Shedinja is handled by the other Pokes, while Surskit... well... Surskit is Uber, so I don't worry too much about it), while Roar will let me shuffle my opponent's Pokes, maximizing Stealth Rock damage and give me a PHazer on the team.
Garchomp @ Yache Berry
Jolly Nature
6 HP / 252 Atk / 252 Speed
-Swords Dance
-Dragon Claw
-Earthquake
-Fire Fang
YacheChomp is an amazing Pokemon, as you all may know. I have been able to Baton Pass Belly Drum to this thing quite a few times, which usually means game, due to the fact that Infernape usually takes care of Sashers with a turn-one Stealth Rock. Even if I'm not able to Baton Pass the Belly Drum, it can set-up with its own Swords Dance and go to town.
Infernape @ Life Orb
Naive Nature
24 Atk / 252 Sp Atk / 232 Speed
-Close Combat
-Flamethrower
-Grass Knot
-HP Ice
My mixed sweeper. If anything goes wrong, he can take the Belly Drum and maximize that amazing Close Combat of his. This Infernape is meant to come in late-game and sweep. HP Ice for dragons/Gliscor in case any of them are still alive and think they can come in freely. Close Combat and Flamthrower are obviously excellent STAB moves (I'm actually thinking about just going with Fire Blast, but I'm still somewhat unsure), and Grass Knot for coverage.
So there you have it. I would like to thank you in advance for any help you could provide me.
