Pokemon White 2: Just beat Elite 4- now what!?

[Treasu(red)]

The Elite Four are ground to dust--- but what's left? Surely my adventure is not over. Can I catch Reshiram in this game, and Kyurem? I checked out the Abysmal ruins and found lots of plates, but don't know what other adventures are awaiting me! Without giving away too much spoilers, can I have you all point me in good directions? I know there's more to the game.

go to the places of Unova you couldn't access before.

Participate in the Pok?mon World Tournament and beat all the Gym Leaders and Champions from Kanto, Johto, Hoenn and Sinnoh.

She already chucked a masterball at me. I wonder what else she has up her lab coat.

Check on a website, i heard there should be plenty of post end game stuff to do now.

Go catch all the Pokemon in the National Dex. One of my friends just did that.

You could do the Pokestar Studios, go back to the first area and raise a pokemon from level one to whatever level you feel is best, fill up the Pokedex, battle with people online.

I'll attempt another tournament soon if enough people participate and actually show up for their battles.
There will be more things that I'll try to do for the community here on TBT that plays Pokemon, but I have no idea what. Sending in suggestions to the group would be nice.
