I agree, the only thing though is it has to have a HP slot, while Munchlax already has 135 HP, so Munchlax's Defense from say Shuckle will be higher, so Dusclops has less HP and Defense on the physical side, but more Special Defense. I would say the best Defensive Eviolite Pokémon are Dusclops (HP), Rhydon (SpDef), Munchlax (Def), Nosepass *original 135 Def and 90 SpD (HP Slot) remember rock types get a Sandstream boost for their Special Defense on top of their Eviolite boost, so they can be used with Tyranitar, etc. to make up for their lower Special Defense stat. For offense, I saw a surprisingly effective Technician Scyther using Vacuum wave in the Special Attack slot of a Mewtwo team. It had Silver Wind, Ominous Wind, Vacuum Wave and I forgot the 4th move, but it was pretty effective, especially as a surprise. During battle it did get +1 all stats boost, and I saw it as a slightly powerful threat. I don't think it has a way to boost Special Attack beyond the Silver / Ominious Wind moves.
