Bones:
Using anger is super risky and I'd advise against it for now. If you need video evidence, I suggest watching my matches at Zenith 2013 LOL.
You drop a ton of punishes on Caroll, tend to laser into approach or dash back into approach and this can get you hit pretty often since you're so geared on approaching. You also play pretty low to the ground and need more FH to evade and to laser.
LOL, well I wasn't thinking about a sort of rage mentality, more alone the lines of a cold, calculated sort of anger. I know in other games when I've been a little pissed off I've played ridiculously good, but I never really thought about why that made me better at the time. I will keep it in the back of my mind not to get carried away with it and just abandon the idea completely if it doesn't seem to be working out.
Rewatching, I'm surprised how telegraphed my approaches were in terms of dashing back, then dashing forward into a laser/aerial. Should I be doing more WDs towards the opponents or simply dashing forward after lasers instead of adding in that extra DD? I actually started consciously adding in a lot of dash aways after lasers because when I would play Peaches and Sheiks I would laser them and get bopped by an OoS option trying to go in too soon. Is the solution to simply space the laser differently in the first place so I can sit still and wait safely, or do spacie matchups just tend to promote more aggressive movement after lasers than floaty matchups? Also, if you could talk about balancing the need to hold bottom mid with the usage of plats, I think that would help me figure out when to use them. Sometimes I jump up onto plats, but then it just feels like I lost stage control because I'm not able to stay under them with utilt, bair, and uair. Do you FH mostly to avoid getting pinned in the corner, or is it a way of drawing the opponent into a certain area so they have to guess between you landing on the top plat, side plat, or dipping back underneath the side plat? There seems to be no method to the madness.
I just used all those paragraphs to say this one thing, and that's please christ don't let me switch characters again just because random pocket marths can **** all over me. This is why I had to stop playing Jiggs, and stop playing Fox. There existed just one character that I crumbled against. And everyone's going on about "Falco has best match-up spread tied with Fox but Falco has lasers so it's easymode". Is it really? Because Marth is a ****ing ****lord character please help
Your first mistake was trying to pick a character based on what you think matchups are and going so far as to abandon two characters because you felt you had a single bad matchup with each...
Your second mistake was not being able to shield fsmash on reaction.
Your third mistake is you probably don't bait attacks often enough. Try DDing just inside of his tipper range and then right back out before he can hit you. If he attacks, you get a free approach. If he doesn't, then that means you could have hit him or at least forced him to back up. He shouldn't be able to just sit still and fsmash on reaction, and even stuff like running up into shield and then WDing out to punish should be super effective vs. any sort of sword swinging.
You also list a bunch of stuff that is easily beaten by being less predictable. If he shields every time you jump at him, empty hop into shine or grab. Cross him up or laser into shine. You can shine on his shield and DJ WL onto a plat. You can late aerial or at least FF to get shine out soon enough. The ideal SHFFL for approaches is usually getting it so you buffer the FF input (3 frame window), but have the attack hit their shield right as you start FFing. If you actually start the FF before you aerial, your aerial won't come out because you'll reach the ground first, and if you start the FF after you aerial, the hitlag will prevent your input from going through. This is easy to practice on a level 9 Bowser with handicap though, so no johns for messing up vs. people. Also, you should be using nair for shield pressure more than dair. It has better frame advantage (I forget the exact number, but we were just talking about it a few pages ago). Not only does it have less landing lag, but the hitbox doesn't stick out below you like dair's does meaning you will land sooner after your aerial hits his shield.
If you get shield poked because you're trapped at the ledge in his tipper range, light shield instead. This buys you WAY more time, you pretty much won't ever get shield poked (especially with shield tilting), and if he tips your shield you slide onto the ledge. The fact that you have more time means he is less likely to correctly predict when you will WD OoS onto the ledge (which is what you should be doing most of the time).
