And Galvanize Explosion/Return/Giga Impact does a FUCKTON of damage, so since Golem's going to be destroyed easily by any of its numerous weaknesses, you may as well give it Focus Sash and just STAB Electric + -ize boost explode.
To be fair, thats how most Rock types should be played anyway; like Ice, they're given defensive stats, abilities, and moves constantly, but their types are way better for attacking.
