This is why you need to check our dub title thread more often, as we try to analyze such things. Hehe. Anyway, it's a pun on "sleight of hand" -- for once, a not-outdated phrase.
On an episode related note, I didn't care for the animation/character designs, at all. They just had to use the really cheap character design for the return of the recurring, now-somewhat serious villains. Bah. It's almost insulting, particularly as the pair has been off the radar since BF, and would have been a nice way to debut in the new region properly (then again, they needed to be obscured, due to their overexposure on the Chronicles episodes). I'm quite used to the cheap animation, but this time, it bugs me.
Yeah, that power double standard annoyed me, too. Cheap Sinnoh parts. Heh.
