So I came across this online pokemon game.

http://play.pokemonshowdown.com
It's pretty fun.
You can make your own team or you can do a random battle where it chooses your pokemon randomly.
If anybody wants to challenge me for a random battle, I'm Dr_Spanky

Its actually an online simulator. Smogon.com uses this one for their matches.

So, basically, it's NetBattle, without all the depth?

It's up to date with B/W2 though.
