This is just a help list. Here you can see what kind of attack you should use to win:
Fire red and leaf green :
You train your pokemon to high levels (When I battled the Elite 4 my Blastoise was on level 70 xD) to about higher than lvl 50 and bring lots of revives and full restores with you.
All you need is a strong fire type, a strong grass type, a strong dark type Pokemon and you should be fine
You can fight them as many times as you want. But every time you beat them, they'll just get stronger.
