critiquing the first vid
i just learnt this, my recommendation is to usually play slow in game 1 and first stock because unless your a reactive player who just reacts to everything your opponent, you'd need a game plan and need to observe their habits/patterns, once you got their pattern figured out, just start making the stuff u need to make like for example, when u dthrow'd Yoshi in first stock, twice, he airdodge'd, i'd probably make a sliding upsmash after im sure he airdodges thinking its safe
unless u were just observing him in first stock, then exclude my holy advice lol,
i like walking sliding utilt, cute lolz.
one thing to avoid STUPID stuff like running into obvious charging smashs, is to stick to ground game because your ground game is 2x better than his, and u have a shield, lol. but just be patient and use common sense like your jab outranges his upsmash (ofcourse from MU knowledge which you'll work on)
generally u want to fight yoshi by camping and u can safely land in front of his shield since his shieldgrab isl ike 17 frames lol, so u can do like a fair > buffered jab and not get grabb'd but he also has oos nair stuff like that.
also sometimes of the inexperienced players tend to not punish when your opponent cross overs your shield (ending up behind ur shield) just takes some observation and punish where hes landing and obv common sense like yoshi would ledgedrop and end up behind u if ur next to the edge. and use more nair cuz he had spotdodging habits
oh and use more jab1.
