^Don't forget Duosion could run Evo Stone 252 HP / 252 Def to have an effective stat spread of 334 HP / 327 Def / 286 SpA / 234 SpD which isn't bad at all considering standard CM Reuniclus has 424 HP / 273 Def / 286 SpA / 206 SpD. You lose out on Life Orb/Leftovers and Focus Blast but it still seems as though it could be a threat.
aaaanyway, looks like I'm going to have to wait until NU comes along before I can make a reasonable Marowak team. There's some really good Pokemon in UU! I imagine the first stage will be very unsettled and will ultimately end with, at the very least, Vulpix being banished. I'm sure none of us will mind if weather as a whole is banned from UU but lets see what happens eh?
