My team is this. I beat them easily

Hitmonchan
Charzard
Snorelax
Raichu
Venasuar
Alakazam

Equipt Hitmonchan with the 4 basic punch attack. Fire, Ice, Thunder, and Mach. On charzard
have Flamethrower, Slash, Smokescreen, and Fly. Snorelax should have Rest, Body Slam,
Surf, and Snore. Raichu is great with Thunder, Thunderbolt, Slam, and Zap Cannon. Venasuar
works wonders with Razor Leaf, Earthquake, Mega Drain, and Cut. And Alakazam should have
Psychic, Shadow Ball, Reflect, and Rain Dance. Hope this helps.
