General Info - This is probably ties with the first gym for title of "Easiest Gym Battle." Like father like son I suppose. Anyways, and self-respecting Water, Ground, Fighting, or even a Fire type like Infernape, should sweep this team without a sweat.

Lv 36 (Steel/Psychic) - The only thing you should watch out for is Hypnosis, but that only has 65% accuracy, and Bronzor is pretty weak to begin with.

Lv36 (Steel/Ground) - Steelix does have a lot of defence so you should probably just use special attacks like Surf to OHKO it. Still, Staraptor with Close Combat could take it down.

Lv39 (Rock/Steel) - Just because a Pokemon with the types Rock and Steel sounds like it would be really tough, both Fighting and Ground attacks do 4x the amount of damage. A Diglett could take this guy out.
