Hmm. Not sure if shinegrab after uthrow on Falcon is legit. Embarrassing noob question here, but does Chile play on a different version of Melee like PAL or something?
They play NTSC. Dark is just too good. Honestly, shine > grab in its various forms are all escapable by Falcon with proper DI and other stuff. It's just better to be u-smashing after non-DI'd u-throws at super low percent (vs Falcon) because it's better (does 18%, leads to knockdown for tech chase, etc). Unless they're by the edge or something. Later on transition into u-tilt (~30%) and use that for a long stretch. U-tilt is ridiculous.
I think there are some funny shine > wavedash > d-smash / d-tilt follows you can try too, but those are harder, probably ruined by DI, less effective than u-tilt, and probably only really useful if you can hit him with the d-smash / d-tilt when he's offstage and go for a gimp that way (so the positioning would be when you're a bit away from the edge, facing the edge).
I know you can shinegrab people that shield instead of spamming multishines for pressure. Racer X from here does that kinda often on me.
Yeah, shine grab on shield is good. Mainly by the edge because a lot of people hold block there for a variety of reasons. Most should be obvious. Shine grab CAN put you at frame advantage versus shield grabbing depending on staling so with proper execution you should be able to trump shield grabs too (usually).
Shine usmash works on the lighter weight characters if I'm not mistaken because of the continuous momentum that fox has after running (chillin shine?) For the heavier characters like Fox/Falco, you can waveshine usmash.
You can shine > u-smash on Fox and Falco, but they can tech to escape it if they're starting on the ground in a standing position. If they're knocked over you're good (I think). If they're in the air, you're good. Proper DI can probably nullify most of this like most janky combo setups.
Let's have someone better than me confirm these things!
