Hard gainer

[mikey]

Quite a few, I found Larvesta a pain to train (lol that rhymed), along with Mankey, Purrloin, Aron, Beldum, and for some reason Chansey.

I guess Ralts is a pain since you have to raise it until level 6 too. It learns Confusion then, soooo. ;-;

Well, that's not of a big deal, since you get it at Lv. 4-5, you just need to send him and switch out those 5-6 times.

I've had an hard time training Crawdaunt in Sapphire. Darn.
At least it was very powerful at the Pokèmon League.

Chansey. Don't ever try raising one for in-game. Unfortunately I have to, since it was given to me for a challenge...and what's worse? I can't evolve it. It's mostly defensive Pokemon that I have trouble with, now that I think about it. Shuckle, Bronzong, Cofagrigus, mainly the likes of those. Though I've never had trouble with Umbreon...hmm. Since this can apply to all games though, I'm going to move it to PGC.

Yeah, shuckle was a pain to raise, but I didn't mind as I actually like defensive types. It's especially fun to pull off a Power Trick upset. ;D
