Hello Smogon, once again, here is a VGC 2012 RMT, from yours truly.
Now, I know around here that theme teams are usually frowned upon, but you can't resist the illustrious charm of a team dedicated to the best Pokemon generation ever: Hoenn! Yes, as many players seem to neglect, Hoenn has some of the greatest Pokemon the world has ever seen. It has the most usable starters, the best legendaries, and the coolest Pokemon designs. This GBU/VGC team is meant to emphasize on this fact, only going for the coolest of the cool Pokemon from the best generation that can counter the many Goodstuff mons out there, which is undoubtedly the most popular playstyle in this metagame, while still trying to regain some originality at the same time.
Sceptile @ Choice Specs
Nature: Timid
Ability: Overgrow
EVs: 4 HP / 252 SpA / 252 Spe
-Leaf Storm
-Dragon Pulse
-Focus Blast
-Hidden Power Rock
Sceptile doesn't get enough love in the VGC format: with massive speed and very usable Special Attack, it's one deadly gecko. Because of Sceptile's naturally-high speed, I decided to go with a Choice Specs set, showing off its true power. Leaf Storm demolishes Gastrodon and Politoed, while Dragon Pulse can deal with Kingdra and Garchomp easily. Focus Blast can destroy Tyranitar and other not-as-common threats such as Scrafty, and Hidden Power Rock will make Zapdos and Thundurus run in fear. Even after the Special Attack drop with Leaf Storm, it still can tear holes in teams with its absolutely unadulterated power.
Blaziken @ Shuca Berry
Nature: Adamant
Ability: Speed Boost
EVs: 4 HP / 252 Atk / 252 Spe
-Flare Blitz
-Sky Uppercut
-Blaze Kick
-Protect
I still question as to why Blaziken isn't more used: big attack, massive speed, and a large movepool, what more could you ask for? Protecting allows Blaziken to get up one Speed Boost, already outspeeding several threats, and hitting back hard with STAB Flare Blitz and Sky Uppercut. Brave Bird takes care of Hitmontop and other Fighting-types that may even try to lay down a finger on this prime gamecock. I was considering running Blaze Kick over Flare Blitz, but I realized that the extra power is absolutely worth the recoil damage. Blaziken holds a Shuca berry just in case ol' Swampert decides to hit him with an unavoidable Earthquake, or to defend from Heatran's Earth Power or Garchomp's Earthquake, putting a big dent in the opponent's plan.
Swampert @ Life Orb
Nature: Adamant
Ability: Torrent
EVs: 252 HP / 252 Atk / 4 SpD
-Waterfall
-Earthquake
-Rock Slide
-Wide Guard
Rounding out the Gen 3 starters is the one and only Swampert, the hobo of a Water/Ground type with many usable perks. The reason Swampert has less speed EVs is because even with them, it can't really outspeed much, so I decided that it could serve as a possible Trick Room counter. Its moveset really needs no explanation, it's a standard QuakeSlide combo with some extra STAB Waterfall thrown in. Wide Guard also acts as a fine supporting move, stopping Cresselia's Icy Wind or other Earthquakes, Rock Slides, and Heat Waves. Life Orb helps boost Swampert's Attack power, but I've considered replacing it with Expert Belt because I want Swampert to remain some of its bulk.
Sableye @ Lagging Tail
Nature: Careful
Ability: Prankster
EVs: 252 HP / 4 Def / 252 SpD
-Fake Out
-Sucker Punch
-Will-o-Wisp
-Trick
In the planning stages, I've considered Cresselia as my support Pokemon, but 1). I'd have three Psychic types on my team then, and 2). If it ain't Hoenn, it ain't any good. So with that, I thought of the other go-to support 'mon: Sableye. Sableye punishes any fool that would even think to attack my other mons, burning them with priority Will-o-Wisp to end a physical attacker's fun, providing good lead support with Fake Out, and striking before they can even attack with Sucker Punch. Priority Recover and Leftovers allows Sableye to stay in longer and foresee the opponent's burn damage pile up higher and higher.
Metagross @ Choice Band
Nature: Adamant
Ability: Clear Body
EVs: 252 HP / 252 Atk / 4 Def
-Iron Head
-Zen Headbutt
-Ice Punch
-Rock Slide
It's the heavy metal itself, the silver glistening tank, and the devastating powerhouse: Metagross. Boasting a Choice Band, Metagross is often used to punish both goodstuff and Trick Room teams alike: with powerful STABs Iron Head and Zen Headbutt to dish out the damage when needed, and Ice Punch and Rock Slide to devastate the Pokemon that once think itself to be safe from Metagross. I originally planned on having it with a Choice Scarf, but I would've needed to change the EVs and nature to have it run effectively, and Metagross is about power, so why even bother when I probably couldn't even outrun a Latios if so?
Latios @ Dragon Gem
Nature: Timid
Ability: Levitate
EVs: 4 HP / 252 SpA / 252 Spe
-Dragon Pulse
-Psyshock
-Hidden Power Ground
-Protect
The final link to my team rounds everyone out nicely, as Latios' sheer Speed and Special Attack allow it to serve as an effective late-game sweeper. Dragon Pulse over Draco Meteor might seem questionable to some, but as I don't really wanna see Latios become a 1-hit wonder and I've seen Draco Meteor miss way too many time, I decided Dragon Pulse was a safer alternative, and it can still OHKO several common Dragons such as Latios and Garchomp with a Dragon Gem. Psyshock is another fine STAB move, and Hidden Power Ground deals with Heatran and Tyranitar, who would normally wall Latios.

Any suggestion to Team Hoenn would be appreciated, but remember it must keep the name with both its usefulness and its mon selection.
