I see! I think this is where we part ways, because I have a knee-jerk feeling that a curbstomp no jutsu earned via groundhog day shenanigans is cheating and doesn't actually count. (I could probably work up some rational arguments to that effect, but at the end of the day it's a purely emotional reaction so I won't try to dress it up as anything more than that. Particularly since some of the curbstomp no jutsu scenarios that I do like are not actually any more fair or plausible. Like curbstomp no jutsu via time travel, for instance... *headdesk*)
