Empty Retribution to SS: Edge (switch to high stance mid animation) is less consistent because they can get out between Empty Retribution and SS:Edge if they don't block, but it's permanently sustainable with double flux.
On the other hand, Skyward blade - SS: Edge - Quick attack - Mind's Edge (switch to high stance mid animation) is very consistent but you have to land it on a grappable human with close to zero ki for it to work, otherwise they'll block the Mind's Edge. Another problem is it simply cost too much ki to do and cannot be sustained for long
