Which is better for a Marowak? I got 3 of them from the Pokewalker. one isn't good natured, another has Rock Head, and the last one has Lightningrod. Should I keep Lightningrod for double-battles, or Rock head for Double-Edge in single-battles. And maybe a moveset. DO NOT include Earthquake! Bonemerang is the same, and it's a Substitute smasher.
