Hmn.. Buy a better Falco... IMO, I think you should work a little on looking before you leap: like, there's a time where you (both) sorta faced the wrong way and attacked more than once. . Lol, I'm a big fan of the "Ghetto Stomp," Where you up A and fast fall on them, Personally I do that A LOT, but I fix a combo in with it. You should try to string attacks together as well.. Hmn... I like how you boomerang to edge guard, but make sure you have you boomerang while you try. Also, Short Hop-Arrows/jump-uncharged arrows help to stop enemies from hitting you. When they're at an angle and you want to projectile them, use arrows.
Try this (I Call it charging):
Pull out a bomb
Throw the boomerang at the opponent.
Wavedash towards them
Use the forward tilt.
throw the bomb
Smash A (Both hits).
After the boomerang hits them is when the attack should go pretty fast. It does damage and it's a killing move.
~Keep up the good work.
