Probably not.
wifi battles battle subway dress up do elite four again link battle (if fiends have pokemon black or white)
ya u can trade Pokemon in blue before u beat the elite four.
The same way you always beat a Pokemon game: beat the evil organization, and then challenge the Elite four and win.
No, you can continue with your game and all
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
