Pretty much the older generations had Effort Ribbons and a lady to tell you if you had the maximum amount of EVs or not, but not in Black.
Not that l see. l'm going to start EV training in Black, but is there even any way to tell if you have max EVs anymore, or you just have to keep really good track?
P.S. l'm sure there is NO Effort Ribbons or any ribbon obtainable in Black or White because when you migrate a Pokemon from an older game with ribbons, they'll be displayed as Memorial01 and so on for some reason, along with the actual name and description on the top screen.
