Yes, but Samus can't do all these things in an aggressive way, spamming attacks like C.Falcon. You have to be careful, Samus is slow, in midair she moves in slow motion. That's why you can't be aggressive like other characters, Samus has her own way. (i'm not telling you "i play safe, i'm better than you" XD)
To me the best thing about Smash is searching the best move to do in a precise moment. The best achievement with the minimal effort.
Also sorry for my bad english :x
Do not worry, english isn't my native language either.
Samus CAN spam attacks in a similar fashion as Captain Falcon or Fox, I am not joking, Samus' F-Air is a critical move that can lead to many things, including a grab, and you can spam that attack with SH as fast as you can.
Also, her aerial game is the most important thing, you can also spam B-Air, and N-Air is good for spacing as the move lasts long similar to Link's N-Air.
One has to be careful not to leave open spots, if your pressure is good, you can make a C.Falcon roll away from you, and that's the point, Dash Attach into U-Tilt can lead into a Charged Beam.
Once, a guy nicknamed "Toti" came to Acapulco, and I played with him, I want to note that his C.Falcon was really good, but with proper pressure I managed to break his defense with Jab cancel>>D-Air>>Bomb Dash>>reversed Jab>>D-Air>>Bomb Dash.
Requires a lot of "clackclackclackclack" with your controller in order to become truly aggressive, not standard aggressive, but truly aggressive.
I also can agree with people that there are certain moments in which you cannot attack directly, for example, when you have been knocked off from an attack and your opponent is Ganon, Marth or C.Falcon, you cannot attack recklessly either, projectiles help me as a decoy, I make them destroy them, and I take that as an open spot to attack, almost always works, also, make them dodge them, it's always a chance.
What I have been implementing, is to always have the Extended Grapple Beam, you can do this very easily from the very beginning of the match, a missed grab, or a SHFF Grapple Beam, that helps you as a second option for tech chasing, for example, Samus Jab cancel is a great pressure and only some attacks from defense can break it, so, most players roll, could be backwards or forward, you just dash-grab and keep the L pressed, and press A anytime, they will be grabbed as long as their animation is over, and I have proved this to work, you can also do a SH N-Air as soon as you know they will jump out of your Jab cancel, so you don't let them move or escape, it's about having always the lead, to think fast and have a solid metagame in all circumstances.
Don't get me wrong, if any of you guys is defensive/campy, I respect your style, if that works to you, keep doing it.
Of course, all of this isn't perfect, there isn't a definitive technique with Samus against anyone, for example, 1233 found a way to break my Jab Cancel with Fox's U-Smash out of the shield, so, that forced me to stay sharp about it and to power shield that move into something else. I love Melee.
Being aggressive always works to me, and I also recall HugS having this to work once against Eddie's Ganon, forcing him to switch, he told me once about this.
I'm glad we are talking about Samus again, kind of gets me inspired.
