Right I'll give it a go then. I should have said the competitive is pretty much BF, but I will post a moveset with a mini strategy. I'll leave you to sort out EVs. I say this because you are better off EV training your Pokemon, but for me anyway my spreads aren't really conventional and are more like what I think is best for the Pokemon I'm using. You pretty much need EVs to do well at the BF anyway. Having said that Smogon has some great analysis on pretty much every fully evolved Pokemon, have a look if you want more ideas etc. What you should note is that I'm giving you a team/ options for the BF, ingame is your choice.
Blaziken @ Whatever item you like.
Adamant/Jolly
-Overheat/Fire Blast
-Earthquake
-Sky Uppercut
-Agility
Deadly attacker, both physically and specially. Overheat is purely a one off move, it plays of his Special Attack which will be hindered by the nature, but still packs a punch. Earthquake is good coverage, Sky Uppercut is STAB. Agility is an option if you want to turn it into an awesome sweeper. If you'd rather not try Rock Slide, it goes well with Earthquake and covers a Flying weakness. You could also go mixed, check Smogon for a good mixed set. I've not used Blaziken in the BF so if anyone wants to debate then go for it.
Gardevoir @ Item. Make sure you get Synchronize Ability.
Timid
-Psychic
-Thunderbolt
-Calm Mind
-Hypnosis/Ice Punch
Another great sweeper, this time a more Special one. Psychic is great STAB, Calm Mind boosts your special stats hence the Timid nature. Shadow Ball is physical in Gen III so it's not ideal on Gardevoir. Hypnosis is good if you want to get some boosts in before you sweep, but it's only got 60% accuracy and the sleep mechanics are variable so you may want to you Ice Punch instead. It gets near perfect coverage with Ice Punch, and will decimate Dragons and Grounds, especially with a CM boost.
Salamence @ Lum Berry
Adamant/Jolly
-Aerial Ace
-Earthquake
-Rock Slide
-Dragon Dance
A really powerful set. Everything speaks for itself. You could swap RS for Brick Break if you want, you get pretty much the same coverage, same power, more accuracy, no Flinch chance but a chance to break Light Screen and Reflect. Will decimate Blissey and Tyranitar which are common opponents in higher end battles. You can ditch DD and go with Jolly and give it Choice Band for some insane power without having to use a turn to set-up. However, you are locked into a move, and if you get statused it severly reduces Salamence's survivabilty, paralyse, sleep, burn and the ever-common freeze most especially. Having a confusion defence also helps
Ludicolo looks great. Give it Leftovers with a Bold/Calm/Modest nature, and you'll be sweet.
I will suggest two great Pokemon I have had some awesome success with.
Metagross @ Lum Berry
Adamant
-Meteor Mash
-Agility
-Earthquake
-Rock Slide/ Explosion/ Light Screen
One Agility. That will set you up really well. If you get good IVs and proper EV allocation you can outspeed even the fastest Jolteon and Aerodactyl, no mean feat. The last slot depends. RS is coverage, Explosion is deadly suicide if you feel you're at the end of Metagross' spell, and Light Screen is a personal favourite of mine because it boosts its Special Defence and provides support for your team too.
Suicune @ Leftovers
*Any nature hindering Attack*
-Surf
-Ice Beam
-Rest
-Sleep Talk/Calm Mind
I post this guys since he's so useful for me. If you can get one that's great, if not go with Ludicolo, or search around the web for another alternative. Surf and Ice Beam are standard, Rest means you love longer. Sleep Talk is good if you don't want to be a sitting duck, CM give you some awesome survivability points. I use CM since if you can get a few of those up (you should be fine since Suicune is an awesome tank) you can wall pretty much anything, and make it Struggle due to Suicune's Pressure Ability. You can swap Lefties for a Chesto if you want to use Rest then get right back into it, but it's one-off which bugs me. I find it can easily survive the Rest time just fine. Suicune depends on your access to FR/LG or Pokemon Colosseum. If you can, get one from Colosseum since the ones from FR/LG have glitched IVs. Up to you though.
Hope that's useful in some way. I would post my Zapdos set but that's unique since I got lucky with a Modest nature and HP (Grass), plus it's from Colosseum so it has Metal Sound. Good luck!
