I'm gonna be honest, I never new spincut could miss
2 years later, just wanna say that, yeah, me neither. Can single techs (that aren't magic) miss, I guess? I probably didn't use spincut by itself very much, since Crono has like a zillion better dual techs that are much more worth your time.
And OK, that part where Scouters kept killing them was hysterical. "What did we learn from this death?" The answer is always "Nothing was learned".
