Yeah I agree with SneakyTaco. I watched the set last night before I went to sleep, so I won't go into as much detail as him. But I just wanted to point out one MAJOR problem I noticed in your play style.
I talked about it before but I don't think anyone ever caught it or talked about it. You ditch your Gyro way too fast. Every single time you get a Gyro in your hands, you throw it away almost instantly. I couldn't count one instance in the entire set that you were grounded and had a Gyro in your hand for longer than 4 or 5 Seconds. You threw it or glide tossed seconds after you had the chance to do so.
Especially against characters like Lucas you need to play patient. He can't kill you from far away, nor can he rack up any % from a distance. His PK Fire sucks if you shoot your Gyro at it or PS it. Also his Up-B is a terrible projectile because you can punish it from any distance because of our Gyro/Laser, or even run up to him if we have the chance.
You should never be the one to approach in the MU, only if we are to punish them, we have no reason to. I mention all of this because our Gyro is the only thing we can combo with when we punish. Throwing it away because you THOUGHT it would come in contact with him gives you no incentive to guarantee yourself combos or a leading %. Even if the Gyro came in contact with him two things could occur:
1.) He Shields it, punishes you heavily, and now you either lost the lead (phucking with you mentally now as well.) or allowed your opponent to increase their lead (giving them more confidence.).
2.) You actually do hit him with the Gyro, what now, you Glide Tossed before you could think of a logical combo or move to follow up with to not only increase your % lead but leave yourself in a much better situation than they afterwards (maybe you're grounded, and they're airborne, etc.).
TLDR: All this is meant to tell you is, please wait and think of options before you blindly attack just because you had the advantage in a situation. Brawl is a game where you can have the advantage and lead one second, and get gimped due to idiocy the next. I want all of us R.O.B's to do better in tourneys, become more well known, actually win tourneys, consistently and become better players overall. We can't do that if we don't think first.
