I do purposely EV train my Pokémon but only those which are supposed to be used online.
For Attack I use the way to the victory road, for Special Attack I use Litwick at the Pokémon Graveyard, for Initiative I use that +2 Initiative Fish, for Defense I use ... wait ... hm ... I don't really know. Sometimes Graveler or something like that in the cave of challenge and for Special Defense I use that new Jellyfish Pokémon.
