EV training after GDC? (spoilers)

[Hannelore]

Hello,

 

I was just wondering if there a list of most efficient ways to EV training after you've gone to GDC and no longer have access to Gearen Lab for awhile? Like best places for training in X stats?

I did some googling but couldn't find anything on EV training that doesn't involve the training rooms. I know there are some tough battles coming up and I've bred and EV trained a bunch of pokemon but I know there will be access to some good ones after leaving West Gearen.

 

Thanks for any help :)
