I don't know if I should comment on the first vids at all. The one vs. the Pika and the MK. The player either lacked a large amount of exp. on the MU(he/she did not know what to do with the naners) or was just bad... ._.
Though I could point out that you are overly aggressive. The whole gt a naner forward > gt the other naner forward strat is old, and it shouldn't work against MK that well, at all. No offense. And the most common habit of all, rolling. It's not the only thing, you also decay your smashes, also pointing out that your opponent had bad DI.
As for the second part, the match vs. the Rob I can again, point out that you were being aggressive, but so was the Rob. The problem here is that you should have switched to defensive, kept your distance and punished during openings. The other problem here is you seemed to be going for flashy-ness? Almost every time Rob was off-stage you went for the spike, the funny part here is that when you could have landed it, you didn't. Your opponent, again, didn't help. He/she made a lot of mistakes, instead of taking opportunities to punish/KO/stage spike you. And....again....you decayed smashes.
For your rolling habit, I advise you to dash and brake with your shield, so you don't risk being pivot grabbed or punished with a strong attack. For your aggressive habit, fight a defensive player, someone whose strat will make you learn to be more, patient(?). For your smash decaying habit, I would recommend to decay Fsmash, and KO with Dsmash, reason for this: Fsmash is DI'able, Dsmash isn't, you're going to suffer trying to kill with Fsmash if your opponent knows how to DI it, specifically the floaty characters
So yeah....scrubby advice but still advice right? :]
