SSBM Soul Breaker Glitch

As Mewtwo, summon a red shell in Training Mode. Using his Over + B to reflect the shell, do this 5 times. On the 6th time, have a character infront of Mewtwo and shield the Red Shell. Right as the Red Shell breaks the shield, have Mewtwo use his Confusion at the same time and it should cause a chain reaction that will have a character stuck inside of him.
