Both XD and Colosseum: Hard to train Pokemon

[Naraku_Diabolos]

I'm posting this thread just to see which Pokemon everyone is having trouble to train. Which Pokemon are giving you a hard time to train? Meaning, any Pokemon that are hard to train due to their weak stats and are underused, such as Aipom, Dunsparce, Delibird and so on. I honestly have trained all of them, weak or not.

Well, on Colosseum it is tough to train some Pokemon who have an overall 'weak' stats to train, such as Aipom. However, my Aipom is Lv50 or so.

I'm having a tough time in XD with my Pineco still since he doesn't have Take Down yet... He still has Pin Missle, which I am still using, but not deleting when he grows stronger. I'm planning on leveling Pineco to Lv50, just for kicks and for him to learn Double-Edge. I'm doing the same thing for Phanpy who learns Double-Edge at Lv49 and Aron to Lv46. Larvitar is the same, going to take him to Lv49 for Earthquake so I can bash up the opponents more.

Hardest in each game? Ok.
Colo: Augh! Aipom! Its so weak! I can't use it! But I want to make them all stronger so then when I trade them they will be so strong, including Aipom.
XD: Chansey. It always faints on me. The other one evolved into Blissey, so I want this one to evolve too. So I'm staying with Chansey.

I think that by still saving the Growlithe and Vulpix from not evolving, it would be a tough time to get through XD without their evolutions. I'm using Roselia still, but I'm heading along with training still in Pyrite. All of my Pokemon are 25-30 each at the moment. Some of them are still unevolved too.
