Ridiculously low damage for how many resources this takes... but it's off of a throw. Requires your opponent to have 2 Dark Sword orbs on them. Throw then shortly after the second hit, press Kameo, EX d,f+3, 2~u+Kameo~2,3, f,f (dash under), b+2,2~Fatal Blow (This string with Light Sword if your opponent has Dark Sword orbs on them causes an extra hit that bounces them and allows you to do Fatal Blow)
