I'm having a bit of trouble edgeguarding falco..
So if you're edgeguarding spacies, as far as I know there are these options right at the edge: downtilt, flareblade, counter, perhaps DED for recoveries going right in your face (as opposed to catching the edge)
If they're so far away that they can only recover to the edge by phantasm/firebird, then I guess flareblade is most reliable.
But if they are high up enough, then then can avoid you by going upwards, so there isn't a catch-all. You have to make a choice between aerial flareblade or dtilt/DED, depending on if you think they will go up or down.
I guess if they are firebirding higher than the stage you can jump out and aerial them right then and there.
What if they are close enough that they can double jump and catch the stage? I guess I could rely on reflexes: If they jump right to the stage, I dtilt, but if they jump backwards (hoping to phantasm/bird), I wait. Then falco has a choice of phantasming or firebirding. If he phantasms towards me, then I can DED him. If he phantasms to the edge, I can dtilt him. If he firebirds, what should I do?
I'll check myself next time I play: Does dtilt work for firebird at the edge?
Does dtilt work for firebird/phantasm towards you?
Does jab?
Does DED?
Does counter work for firebird at the edge?
Does flareblade come out fast enough to use it on reaction if I see a phantasm? How far back do I need to be?
Ideally I just flareblade and react to anything that comes my way except firebird above me...
Some of it relies on my reaction time only- but that depends on knowing the options as well.
