It's after you beat the elite four. Don't worry, you can't miss it!
After you beat the elite four, there's a zoarak out side victory road . Follow that zoarak and he will lead you to n , n gives you the black stone in pokemon black , and the white stone in pokemon white. Get the stone to dragonspiral tower and it will revive. Catch the legendary pokemon and then find kyurem in giant chasm. Before you beat the elite four, you will have to beat white/black kyurem after you beat it, there's the gene wedge on the floor.use that gene wedge to fuse reshiram/zekrom to kyurem to get black/white kyurem.
there are no specific Pokemon that can automatically beat the elite four. HOWEVER, ( i speak from experience) i beat the elite four with one Pokemon whitch was Samurott. i suggest using Samurott 2. hope i helped! :) - Raven

If you have Pokemon White then you get Zekrom right after you beat the elite four for the first time inside N's Castle. If you have Pokemon Black then you get reshiram right after you beat the elite four for the first time inside N's Castle.
