Mean Look is a VERY good option over Confuse Ray on Sableye's standard set.

Mean Look is great for trapping stall, support-mons like Bronzong & Deoxys-S/D, and most notably Tyranitar & Scizor once you burn them.
What most people don't realize about this set, if they haven't been playing Dream World OU at all, is the EVs. It looks very thrown together, but it actually allows it to take hits from both sides reasonably well and perfectly take specific hits from OU threats. For instance, Choice Band Scizor Bullet Punch will do 57.6% - 68.1% to Sableye meaning that if Sableye burns it after it's first Bullet Punch, Sableye is never 2HKOd with Leftovers. The reason that is important is Scizor is one of the few Physical Attackers that can hit Sableye before Will-O-Wisp burns it. If it doesn't run enough Defense, it will be forced to switch-out and come back in with less than 30% of it's HP left regardless of if WoW hits or not.
That's one big reason Sp.Defensive Sableye isn't standard in DW even though DW has FAR more Special Attacking threats than Standard OU (Serperior, Genesect, Keldeo, Swift Swimmers, Zapdos, etc.) but probably the biggest reason is that it doesn't really threaten Special Attackers at all. It might have a shot of stalling them out, but 50 Base HP & 65 Base Sp.Def really bites it in the ass. If you ever need to switch Sableye on a Special Attacker, you're far better off using Stun Spore Whimsicott or Haze + T-Wave Murkrow. Whimsicott at least has the typing to handle Special Attacks where Sableye has nothing it really needs outside immunity to Focus Blast & Psychic. (Normal/Poison is just a terrible immunity/resistance on the Special side.)
Whimsicott & Murkrow are about stealing momentum. Not Sableye. Sableye is about complete preventing momentum or stopping it very early on.

Even though DW has new threats, most of the current Pokemon in OU remain completely unchanged down to their EVs unless they got a new ability. Really the biggest difference is no team preview & Swift Swim, which just makes Grass-types & Water Absorb more common really. I still think DW tier is a really bad idea, (fun though) but PO's usage stats are a very good and VERY overlooked source of information regardless.
