I use this set a lot, and it does work. I use Flame Charge to get a speed boost, and type coverage. Automize is another option, but it weakness the damage heavy slam does, and also does not give you type coverage. Heavy slam and earthquake are just two amazing attacking moves. I just put a metal coat to boost heavy slam even further, though it could hold anything,as long as it is not a choice item. If you were to put on leftovers, Leech seed could be replaced with another attacking move,
like double-edge, or brutal swing, as long as it is physical.
Once this thing has 1 or 2 boosts in speed, and 1 attack boost, it is basically unstoppable
