Quite frankly, I'm disgusted with the lack of THUNDER WAVE + ROCK SLIDE mentions around here. After a T-Wave he will out speed damn near anything in OU without any speed investment. Sturdy guarantees that you get off your status move. From there, you can either set up Stealth Rocks, fire off a powerful steel type attack or coverage move, or (last but not least) flinch hax the fucker to death. This combination makes Aggron one of the scariest Stealth Rock setters around. His only real fear are pokemon with Magic Bounce (aka Mega Absol (which nobody uses) and Espeon (which is easily trapped and KO'd by Pursuit users)).
tl;dr Not using T-Wave and Rock Slide is pants on head retarded.
