Event 51 story time
I was trying to beat this for about an hour with my mains, shiek, ness, and marth, but I couldn't get it done. Then I realized...Jigglypuff's rest would mutilate Giga Bowser. Even then, being a mostly causual player, I could kill giga bowser, but ganondorf and mewtwo would get me. I managed to kill giga and only lose one stock, and I took out ganondorf with one stock remaining, but mewtwo had two stocks to my one. I managed to take out mewtwo, but with my 50% to his 0%, I thought I was done. I managed to get 30% on him before he hit me. I had 70& and he was charging his shadow ball, and I thought it was over.
Then it happened.
A bomb-omb flippin spawned right above his shadow, and KO'ed him, winning me Event 51. This taught me two things.
Better to be lucky then good, and bomb-ombs are flipping awesome. (Gave me more proof that items are bad for the competitive play).
