Everyone still neglects bomb jumping, it's a shame, really. I strongly encourage all Samus players to try inputting it into their game, to some it may seem useless, but you have no idea.
Brawling with KingChaos, I found an even more importance of using Bombs, even when in the air. I look back at some of my replays from before my matches with KingChaos, and I see that I seldom (or rarely) ever used my Bombs. That's not to say that I didn't use my Bombs to save my second jump to return to the stage, but that even when I am above and away from the stage, Bombs still have their importance to safely return.
I knew that tune was all too familiar.
Energy Tank from OC Remix. Next time throw in
Zebes Rising. It's also the Red Brinstar theme. I liked how you used your z-air. That was very impressive. I saw in your video where you used your Grappling Beam to return, but 618 was hanging on instead. Sometimes it's simply a reaction to use the Screw Attack, but remember to use Bombs and then the Screw Attack once you're in a good position to return safely.
