In other news (which is definitely related, for being an amazing glitch), thanks to the Transform/Rage glich in Generation IV, Slaking can learn Skill Swap (Unless the glitch works differently in his case). This opens so many frontiers of Destruction, it's not even funny....wait no, it is.
BWAHAHA.
Evil laughter aside, it certainly is surprising that the one thing that could make Slaking too godly to exist has no posts here....
However, the possibilities are definitely worth noting here. Pop Truant on any opposing pokemon, and you force an automatic switch. Trap them first, and you're in for shmooth shailing with Focus Punch and Protect. If Swapking doesn't get banned, Ariados and other trap-passers will start seeing a lot of use.
Now all that's left to do is for good ole' Smogon to decide on how to deal with this game-breaker (although i may be speaking too soon).
Swapking needs a tier of his own.
