Hello guys
After like 10 years have passed, my cousin and I took up a challenge to pick our old pokémon red and blue cartidges, start from scratch and have a huge fight in two weeks.

BUT, he doesn't know that I remember his exact team from the time, and I'm sure he'll use the same one.

>Blastoise
>Muk
>Gengar
>Dargonite
>Machamp
>Nidoking

What team should I build in order to destroy him ?
>Legendaries are not allowed
>He'll use the Red version, and I'll use the Blue one

Thanks /vp/ !
