I moved this to RMT

ok

Alright, first off, I suggest using sprites for your RMT. Refer to this: https://poarea51.forumotion.com/t43-how-rmt-should-look-like for more help. Or, you can use PokeBattleCenters very convenient ERMT, http://pokebattlecenter.net/ermt/, but this is totally optional. It's been proven, though, that more people will rate. Lets get started, shall we?

First off, I suggest using a set like this for Archeops. Run offensive EVs, and change to Jolly or Adamant.
Archeops (F) @ Flight Gem
Trait: Defeatist
EVs: 255 Def / 255 SDef
Hardy Nature
- Head Smash
- Dragon Claw
- U-Turn
- Acrobatics

For Keldeo, Offensive EV's (252 Sp Atk, 252 Speed), because why attack, when you have no Physical Attacking moves? I suggest running a Calm Mind set. You can run Secret Sword, Surf, HP Ice, and Calm Mind, or you can try Substitute over HP Ice, but I don't recommend this, as Jellicent will wall you to death.

For Cobalion:
I don't like that idea at ALL. If you want a steel type, try running Heatran. You'll like him a lot more.

Virizon:
You might wanna try Calm Mind, but that's just me.
I think a defensive set might work, but for me, if you are using CM, regular ol' SP atk evs. :/

Terrakion:
I suggest changing Lefties to Choice Scarf, and all EVs to offensive EVs.

Garchomp:
Don't
Ever
Run
Defensive
Garchomp
Try Swords Dance, Fire Fang, Outrage (or dragon claw), and Earthquake
Change the EV's to offensive, Defensive Garchomp won't work. Trust me.
Make his nature Adamant or Jolly.

Sweetie i like the rmt website... it saves a lot of time (:
