Somedays i just SUCK ***
other days i move really fluidly
i suck at consistency.
its not like tech skill problems though (usually) it's strategy/mental issues. I know most matchups, sometimes i play them right and sometimes i just...don't.
halp?
I used to be like this. Basically, I learned that all you really need to do is get better tech skill. You see, what happened with me is that I would get really pressured in intense matches, which would make me mess up on stupid things, like even just trying to n-air out of shield I'd end up rolling or something stupid. Anyway, I would just get more frustrated and need to stop playing for a while. Then I just took like a week or so and practiced the ATs so that I did them absolutely naturally. And guess what? The next time I played against my friends I held my own when things got intense. I also learned to tech in place mainly with Falcon (thanks to some great advice from Elen) and I got techchased a lot less, which helped me to focus on what I was doing.
The simple thing is that the more control you have over your character, the more options you have available to you. You don't think to do crazy things because you can't do them. If you're having trouble doing simple shffls in the middle of an intense match, you're definitely not going to be going to try to mind-game them. Just focus on trying to do what you're trying to do. That's the most important thing in smash. Don't be focused on the whole set or match or stock, but just one move at a time. Have a plan in mind, but realize that you can only react to what your opponent does. With Falcon I stopped trying to do really ridiculous things like triple knee. Instead, once I kneed them once and saw they were in range for another, I'd go for a second one, and if they were still in range I'd go for yet another one. Likewise, I got a ton better at tech-chasing just by guessing. Sometimes I down-air to the right when they tech left, or sometimes I try to jab them out of a missed tech and they roll behind me. But honestly, there are about four options they have: Tech in place, tech right, tech left, or don't tech. If you just guess you have a one in four chance of continuing the combo. And a lot of the time missing the tech and teching in place are the same if you're going for an aerial instead of a grab. It's really not as complicated as it sounds. And getting a feel for what your opponent typically does helps a lot, too. I know that if Chize techs right and I grab him and d-throw him, he's probably going to tech left right afterward and I'll go for a down-air, regrab, up-throw, down-tilt, knee. Bam, a pretty good combo all because I guessed.
Here's the shortened version of what I'm trying to say: Keep your cool, but have your tech-skill be good enough that even if you lose it, you'll still be able to do what you're trying to do and regain control of the match. Practice tech-chasing just by guessing and then mature to making educated guesses based on what you've seen them do in the past. If they miss the tech on a down-throw once, try jab resetting the next time. Maybe they're not used to the timing and need to figure it out. Abuse that. Learn to do really crazy things. The more options you have available, the more unpredictable you can be. You should learn to have complete control over your main. But above all: Relax, it's just a game. Play to have fun. I do ridiculous Falcon Punch combos (such as down-air to knee to Falcon Punch or reverse Falcon Punch to double knee) because I throw them out at times when I think I've got a shot. In fact, I switched to Falcon because I had more fun with him. It gave me motivation to become better. Remember, if Melee's becoming more about this abstract idea of becoming better instead of just having fun, then you need to seriously re-evaluate why you play.
tl;dr version: Chill out and practice tech skill, you'll get better eventually.
