Question

Can you catch Arceus or Jirachi in Black/White 2?

Comments

If you get me something good enough, I can trade you jirachi from my white 2 game over wifi. I have no need of it. Just let me know if you want it. (by commenting under this)

Answer 1

No not currently. Though they may be avalible through Dream World/Events in time to come.
Here is a link to all legenderys avalible in B/W2.

Answer 2

No, you can't.
But these are the legendaries you can catch.
