BW/BW2 How to obtain the National Dex in Black/White

[Card Slinger J]

In order to obtain the National Pokedex in Black/White do you have to obtain Zorua and/or Zoroark first or does it not matter?

 

[Rusty Sticks]

You just have to beat the game...no matter what you have on your Pokedex.

 

[PMJ]

Yep. It's obtained automatically during the beginning events of the postgame.
