5th Gen How can I train the s**t out of my team.

[Underi]

So me and my friend decided year ago to have a duel in b&w. But starting from scratch. We had a few rules; no legendaries and no pokemons from older games. I have my team already, but I don't know where to train anymore. I beat elite four ONCE so they would give some training again but thing is 4/6 of my team is under lv 50 and those two are lv 50 and 52. My team;
Samurott lv50
Archeops lv49
Reuniclus lv48
Scrafty lv52
Bearyic lv46
Galvanyula lv46
plz help

As the post above said, the areas in east Unova (postgame only) have Audino in the late 40's-early 50 level-wise so if you can withstand them (such as their powerful Double-Edge) they are good for training. There are also rematchable trainers in Nimbasa City's sport stadiums that change every day.
