Well... you could use a slow sweeper. Curselax comes to mind.

-Rest / Selfdestruct
-Crunch / Fire Punch
Ok, if you're able to set up, you're going to rape teams. Return for powerful STAB, Body Slam if you like the paralyze chance. Rest or Selfdestruct is hard to decide nowadays: While Rest means full recover, you sleep for 2 turns, so the opponent can set up against you. Selfdestruct you...blow yourself and kill the opponent.
Now, the last move is a tough choice. If you go with EQ, will hit everything hard, except Ghost Levitators and Skarmory. With Crunch, Tyranitar rapes you, but you hit the ghosts pretty badly. Fire Punch gets good coverage ( could try Thunderpunch or Ice Punch too ).
