Im gonna go by the second video.
First off I hate wifi.
Mother of GOD. You know why I hate wifi? Because when you grab release a meta knight and choose to dolphin slash him, you shouldnt be getting hit by an 8 frame start up move in the process. Rant aside, lets go!
Let me start off by saying your spacing is not intimidating. Doing rising retreating fairs like you were doing get you no where and have enough cool down for Meta Knight to dash grab you (he never did). Alternatively he could try to shield (powershield makes it more effective) it and forward roll to lol at your lack of options (something similar to this is at 2:35). Why set yourself up like this?
What do I mean by intimidation?
You are moving so you stay outside of their immediate range (remember we do outrange him in a lot of kooky ways) and NOT throwing out aerials that would DEFINITELY WHIFF. This means using our aerial mobility and walks to realign ourselves in this baiting contest you both set yourselves up to have. When one of Marths scariest things in the match up at low percents is him [power] shielding something of MKs for a grab, you seemed to show to me that the action itself was not apart of your repertoire. Not until after you got hit did you start trying dash to shields but you always did so WELL OUTSIDE OF HIS RANGE, ensuring that it was not in any way pressuring (as he wasnt going for dash grabs anyway) but also giving you the lag of the stop in ground mobility and the shield drop... you also always spot dodged or rolled back, with both being dash attack and the former being ftilt fodder (dash attack being REALLY DANGEROUS to get hit by at low percents).
To sum it up, you need to really fine tune your pressure and spacing.
You also showed to have a bad habit of landing into your opponent (0:43) or air dodging early ! AND holding forward during their hits so they had better follow ups (0:15 - 36,
FIVE TIMES including the roll, and only ONCE did it work out for you)! Smash DI is quite an amazing tool used to great effect by the best players, adding it to your game when you know you are going to get hit can reduce the amount of damage you are being inflicted by in attack strings. Yes, getting the muscle memory of spamming quarter circle di in one direction is PRO.
Often in these bad positional situations you would be in you would NEARLY ALWAYS throw out grabs! UGH!!!!!!!!!!! MK would seriously just jump over your head and you would try grabbing
You need to add the instant ledge grab technique into your game so your ledge options are... in lack of other words... BETTER. Giving yourself moments of time to gauge your opponent (draining shields from them reacting to you ledge dropping or you seeing they arent shielding so you hit them, etc etc, more mix ups). Even though you mixed up your ledge gets up everytime, Sanoscy seemed to always know what you were going to do and punish you for it. Id say thats because of how much invincibility you are losing from non-immediate buffered get ups (hence why the instant ledge grab is useful for regaining your invincibility in this).
So:
Tune your spacing habits and your options in doing so
Instead of rolling backwards as often as you do, learn about the power of dash away reverse dancing blade, which pretty much is the exact same option minus the invincibility but better speed and LOL IT HITS PEOPLE.
Stop air dodging SO early or after getting hit trying to air dodge into someone.
Add some patience into your game play. Sanoscy (and a lot of players in general) spot dodges alot in a semi-pressuring situation, such as ff aerials on his shield or his tornado ending or a whiffed attack. The sheer fact that if you chose to expect something like that ONCE or TWICE out of the many times that you could have gained a lot of extra damage.
Sorry if my critique seems a bit harsh !_! I really like critiquing marths who have a good understanding of the game, and hence put a lot of effort into them.
