Okay, I'm watching you against Falco on Dreamland.
...the fake Mew2King tag is kinda lame.
At 0:13, you shoulda fthrown him. Uthrow would obviously have taken him to the platform, where the most you'll get is probably just a utilt, since Dream Land platforms are so high up.
Anyway, after the fthrow, it'd just be tech chases. If they tech in place or away, run up and grab them, fthrow to dtilt and there's the edgeguard. If they tech behind you, pivot or turnaround grab, dthrow, and it starts all over again.
Speaking of pivot grabs, they're good to learn to use.
At 0:29 you shoulda done what Taj calls "blowing out the candle". Basically, just go out there and hit him with the Dancing Blade or a fair, and he dies. Simple stuff.
It's cool that you can wavedash out of shield, but maybe you should consider doing something other than wavedash fsmash. It's kinda predictable after a while.
If you're having trouble with the chaingrab, try fthrow to regrab to uthrow. It'll give you a little more percentage and therefore, more time to react.
Wow, DI out of Falco's combos. Don't let him just smack you around.
Dash dance to wavedash to shield with your back to Falco? Seriously?
