Post elite four...

[PKMN Legend Anthony]

I've just completed the elite four and activated the poke shifter. I've transferred all my pokemon and had a few battles and I now find myself at a loose end.

So my question, what is there to do after you completed the unova league?

Do random junk just like in all the other Pokemon games!

You can visit Black City/White Forest.
You can chase Legendaries.
You can battle more.
Etc.

if haven't done so yet you can take on the Battle Subway for BPs which is the GEN V version of Battle Tower.
I read on serebii that after you beat the league you can do something called battle testing.
