As a huge ghost fan, I have been using sableye, as well as the other ghosts, since the beginning. It's sad sableye can't get both Recover and Metal Burst. However, I did think of a good moveset for him.
Sableye@Chesto Berry
Brave
252Hp/136def/136spdef 0 speed IV
Mischevious Heart
Metal Burst
Rest
Confuse Ray/Will-o-wisp/toxic
Sucker Punch/Shadow Sneak
With this set Sableye can use Metal Burst at least twice, more if you have heal bell support. With the stats, Sableye will always attack last with Metal burst, but first with Everything else thats to that great ability. If anything survives Metal Burst, a Sucker punch or shadow sneak will finish it off. Confuse ray/Will-o-wisp/toxic all all there to help annoy the bad guys if you don't want to rest it up.
