I think fast. "Volcano, use SmokeScreen!"
Smoke erupts from Volcano, filling the nearby area. It was dense and sooty. It was hard to see, but we made out escape while the Aggron was choking on smoke and the Magneton's radar-like eyes were obstructed by the smoke. I distanced myself away from the magnet-like ball to avoid anymore run-ins with the steel types. Luckily, there was a detour leading to Satellite Pier.
