actually, no. it is somewhat possible. if u have counterattack, mimic, and enemy lure, it is possible to do something other than omnislash. if u have enemy lure, that lowers ur luck and chance for pre-emp attacks. therfore u attack w/ counter, but u could hit mimic afterwards and just do another cut. or another possibilty is... have final attack materia paired with pheonix, and then have enemy lure. sephiroth (ME ) will attack first, if u have no hp plus materia (which is very dumb) he will kill u. u will then use final attack and summon pheonix, u will be rivived, BUT HAVE AN EMPTY LIMIT GUAGE!!!! but the part about Lord Sephiroth (respectively ) using omni-slash is a bit unbelievable. but who knows, he might know it, i dunno, i beat him in one hit, and besides im the ffx master here, not ffvii. and if u do the thing with pheonix, u could also use knights of the round and beat him, ive heard that works too. ive rambled on enough. later
