What Pokemon make up the hardest to train team in Pokemon Pearl, Diamond, and Platinum?

Question

I really love playing the older games, and with OrAs long been released and the new game being revealed soon I've been getting a bit bored with Pokemon and have been looking for a challenge. I have Pokemon Pearl and was wondering what Pokemon are especially difficult to train in the trilogy.

Any and all Dragon-types. A team of six Gible. DO IT!!

Answer 1

The following are the Pokemon that come under the Fluctuating Experience Growth group:

Shroomish------->Breloom
Corphish-------->Crawdaunt
Drifloon--------->Drifblim
Gulpin--------->Swalot
Makuhita------->Hariyama
Wailmer-------->Wailord
Illumise
Seviper

All of these except Seviper can be obtained easily in-game. All these Pokemon require 1,640,000 experience points to reach Lv 100.
