Strategy
Try starting with Diglett to evolve to Dugtrio and have a line of defense (if you roll faces).
In the meanwhile, prepare a bench of Marowak, Machamp ex and Marshadow.
Marshadow gives you a way out if they're too fast at big attacks.
And Machamp Ex is a great way to finish stronger pokemons (Because of its 120 attack)
Hitmonchan is more of a panic button or a line of defense if you don't have dugtrio.
