Chatot maybe?

Chatot Timid (+Speed, -Sp.Attack) 255 Sp.Attack/ 255 Speed (Approx. 140 Sp.Atk, 155 Speed) Salac Berry (+ 50% Speed when below 50% is reached --> 225 Speed)

Heat Wave Chatter Hyper Voice Endure/Substitute (to activate Salac Berry)

The only problem with this Chatot is that he would have to be on a separate team than my Medicham, who will also be using a Salac Berry for the speed boost.

HG/SS Game Plan

Crawdaunt (Water/Dark) -- Corphish
Hypno (Psychic) -- Drowzee
Camerupt (Fire/Ground) -- Numel
Scyther (Bug/Flying)

I will be transferring this team over to the game ASAP, and then using them only. I think I'm going to have to send them as eggs just so I won't have the boosted exp problem bonus, but that means I have to run around and hatch eggs.

Even though I hate Numel because that was my bracelet pokemon at the tournament this past summer, at which I was not chosen.
