It depends on what your team is. You just have to simply train it until it learns good moves. Try teaching it some TMs or HMs. It may take a while but it will eventually get better. Assist can be very helpful if your pokemon know some very powerful moves as well as Shadow Claw Night Slash and Slash. Good luck.
you beat the game and it's gone sure to bring Pokemon in the sixties as trainers are super strong
It really depends on the Pokemon that you have. Use level 100 Pokemon if you have any (if not, use strong Pokemon). Also, use super-effective moves.
Ground is super-effective against electricGround type pokemon.

The good rod is unavailable in Pokemon Black and White. Instead, when you start the postgame Looker will give you the Super Rod.
Timburr is a fighting type so psychic and flying are super-effective.
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.
