Sorry for slow response, slower computer, okay well if you ever decide to do some serious EV training let me know and I'll help. As for the Glaceon just ride your bike up and down the long strip of land BELOW the breeding center. Sorry I don't remember the name of the town but I have'nt played pokemon in weeks.....
If you've kept a log of what you've done with Luke's EVs then finish them(if not already done) then just go fight the strongest pokemon you can( that does'nt take forever to beat) and you'll be done in a week or a few days depending on how long you do it each day.
I don't EV train either. I use a Macho Brace, but that's about it.
Scarlet almost always freezes her opponents. That's why I love her.
If you want to battle again, I'll be using the same Pokémon. Unless I can finish Cacturne's training.
