The best tip I can give is that you need to train more and for Stage 51 it may be best to use Kirby or Jiggelypuff because they can jump the highest while staying there long enough to get away from the upcoming punches (except some attacks) or Peach because she can hover a little while.
Learn the movements from both hands so that you can see what kind of attack they possibley can prepare themselves for.
Kirby's Rock form is good for making sure that alot of hits won't hurt you at all, but timing is essential.
Samus would be good because she doesn't have to get near to do heavy damage with her missiles and especially Energy Ball.
Myself, I use Roy and use a fully charged (or partially, depends on what the other hand does) Up+A to do major damage, but you need to be charging up when the hand that you want to attack is moving back to its begin place and release when its there and then move the hell out of the way for any attacks it will prepare for.
