So, I'm currently creating a team for Ranked Doubles Battles. I need some advice on how to fine-tune it. Mind helping me out anons of /vp/?

Timid, Trace Gardevoir

Held Item: Gardevoirite

Psyshock
Thunderbolt
Shadowball
Moonblast

Jolly, Rough Skin Garchomp

Held Item: Still Deciding

Earthquake
Dragonclaw
Iron Head/Crunch (Which one is best now that Fairy is a threat?)
Protect

Adamant GW Talonflame

Held Item: Still Deciding

Flare Blitz
Brave Bird
Sword Dance
Protect

Adamant Poison Heal Breloom

Held item: Toxic Orb

Mach Punch
Seed Bomb
Spore
Protect

Timid Gengar

Held Item: Focus Sash

Shadowball
Sludge Bomb
Thunderbolt
Protect

Adamant Tech Scizor

Held Item: Don't know yet

Right now, it's nothing but hyper-offense. I need to introduce a bulky support Pokemon to the mix, but don't really know who to drop and who to add. Was thinking of going with a Special Wall Blissey but don't know how that'd fit in with my team's synergy.

The only Pokemon that I really want to keep are Talonflame and Breloom. Those two guys have saved me on more than one occasions with either Spore, Poison Heal, and GW Bravebird. M-Gardevoir has also been doing a pretty good job on my team and has even swept a few times, but I'm open to a better moveset. I can't wait until Hyper Voice is in Gen VI...

Any suggestions (Even if laced with sarasm and ridicule) would be appreciated! Thank you anons of /vp/! In return, have some cute Eeveelutions.
