Overview
THE premier Ground attacker of Gen 5. Excadrill can enter the field and immediately have a 405 Attack paired with a Speed of 550, no set-up required. Add on Swords Dance or Choice Band and you can almost smell the fear of opponents.*yuck* All three Abilities are very beneficial and can all be utilized in OU. There really isn't a whole lot to say about Excadrill except that you should expect to see a lot of these running around in Sandstorm teams.

Very simple concept here. Bring Excadrill in during a Sandstorm and have a field day. Set-up Swords Dance when you expect a switch. Sand Rush instantly doubles Excadrill's Speed during the Sandstorm. Rock Slide hits those Flyers unaffected by your EQ. X-Scissor or Brick Break for coverage. Grass-Psychic-Dark coverage vs. Normal-Dark. There really isn't a lot to explain here.

Is explanation necessary? Get in and KO stuff. With Sand Rush it's like the SDer without ability to change moves, while with Sand Force it can take out most counters on the switch. The given moveset is probably the best, as no Pokemon resist all of them.

Rapid Spin is also an option in your set, if the utility is important.
