Why do all people like speedy atkers? I know Jolteon can be sp.atker but you don't need speed to win everything , there are moves called PRIORITY MOVES that can beat Jolteon of not a sturdy defense as Ampharos does, Ampharos can hit like a boss but also has good defenses so Ampharos can last a pretty long battle. Plus it has lots of potential to OHKO most Pokemon except ground types.Note this is opinionated.
