well i beat the elite four with one Pokemon that was at level 60.
That's entirely up to you
Have a good Fire and/or Ground Type...
lance is the champion in the johto league, after beating the elite four you will face off against lance.and his Pokemon are really good.
There really is not a best Pokemon that stands out above the rest. in fact, any Pokemon that is really high lv can kick butt. though legendaries are good for beating the elite four
There is only one rod in Pokemon Black and White. You will receive it after beating the elite four. It is the SUPER ROD. it lets you catch a ton of new pokemon.
you unlock the extended part of the safari zone after beating the elite four. you can catch really good Pokemon like houndoom, tauros, teddirusa,etc.
you shood stock up on potions and revives and also keep training your Pokemon
Well, if I where you I would use it on Mewtwo in Cerulean cave after beating the Elite Four when the guard is not there, another good call is to save it and if you get any event Pokemon use it there
get some good pokemon with good move
the elite 4
good Pokemon
You have a very good team!! I would try the Elite Four, but you may be defeated. Try getting all of you Pokemon to lv.50 then beating the Elite Four. Stock up on Revives and Potions.
