Started a guide. Guides are harder than I thought.
On the topic of mindgames... Heh. It's kinda impossible to beat someone like Sethlon without mindgames. I have plenty, but they're not as consistent as Tombo's Id imagine. I use lots of frame traps on shield and have a solid list of approaches and such, plus a large wealth of... unique situational knowledge due to all my time as a Melee Yoshi.
Oh, and on uair strings, they DEFINITELY have their place, but mostly on fast fallers, more on floaties than you'd expect. In PM I use uairs more after utilt wont reach, so you have to know when the utilt will whiff and finish off the combo with uair string>fair or something like that. I was just doing this a few minutes ago.
And, ugh, I hate that I'm starting to use Side-B, but I labbed with it for like an hour. Side B is faster than dashing once it gets going, so lets say I'm on the left side of FD... I down smash my opponent in to the stage, who's at 120%. I can't get to the other side. Fastest way to get there? Side B. Now, the fun part comes with the trick of side b-ing so you snap to the ledge! The goal for me is to get the explosion hitbox, then a few frames later grab the ledge. I've been using this a lot, and through doing so I've found this can also add to Yoshi's plethera of pressuring options, even though it's stupid cheesy. I hope it gets nerfed, it's stronger than I want it to be... Anyway! Tonight at IaB I'mma try using side-b more. I think it has potential in some spots.
