Stop trying to shield grab as much against spacies.
Actually
Not claiming that I watched all the video footage (just the last link) but I saw him use shield grab at least once on the strong hit of their fsmash. You actually have a frame advantage here for a grab, so in theory it's totally safe. It just requires that cory gets his timing down a bit faster, ey cory
Grabbing against FFers is a very high risk, very high reward mechanic. You get fox/falco in an uthrow and it's pretty much a free 20/50% depending on how you follow up. considering that samus's gimp game starts to work best right around that mark, you might as well justify that as a potential stock.
Unless you miss and get Usmashed by fox. Not cool.
One thing I saw was that you have a hasty recovery. I fall into this bad habit all the time, so hopefully by telling you not to constantly try to catch them off guard by hitting them with an early screw attack upon recovery, instead of safely sweetspotting and grabbing onto the ledge, it'll reinforce that in my own head and I can stop doing it too.
I'd be slightly more careful with your screw attacks. They work nice to effectively reset the battlefield to zero, but samus doesn't get enough out of them to be used as an offensive spacing game. That's what WD tilts are better used for. I just saw you missing screw attacks, or just barely giving fox/falco a love tap with them. Dangerous stuff man
lol all those missed charge shots :C
remember that uthrow combos into it. You gotta do the sexy little midair turnaround to get them though. It's so clutch.
If I had to nitpick once more, you had some nice spur of the moment edgeguards and decent missileage but I think you should get a bit more consistent and aggressive with them when you're edgeguarding, especially against fox. They're so vulnerable when off stage, it's total advantage samus at that point. Let's see some feet out there. Be really gay
