This may seem like a weird set at first, but with sleep's changes in gen 5 this is more viable and deadly than ever. With things such as Breloom and hypnotoed being pretty popular, this Conkeldurr can be a true monster. Switch it into any sleeping move and sleep talk away. The advantage over normal CB Conkeldurr is that it is technically not locked into one move and that it is unpredictable. Additionally, you are often forced to switch out CB users which works to your advantage with this set as it resets the amount of sleeping turns.
Superpower is to ensure the OHKO on many things and would be used over drain punch or hammer arm, although this is mostly a personal preference. Payback is a no-brainer; fighting + dark provides near perfect coverage and hits ghosts for super-effective damage. Thunder punch is the first option as it also hits Jellicent, meaning that you have a 66% of hitting Jellicent for major damage as opposed to 33% with ice punch instead of t-punch. Ice Punch can nab an OHKO against things like Landorus-T and give you more chance of killing defensive Celebi whereas Stone Edge is an inbetween option, but the 80% accuracy is a bitch.
Your opponent cannot outpredict you as there is nothing to outpredict; you are going to hit his switch-in with any of 3 moves off 936 base power and superpower hits everything extremely hard thanks to 180 power after STAB.
