Someone give me an overview of Falco's customs por favor. Which ones are good and in which situations are they good?
Blasters: are they all trash?
Side B: is phase worth taking in matchups where you get edgeguarded?
Fire Bird: is the default the worst?
Reflector: in which matchups should I be using default over void?
These guys made a video on their impressions on Falco's customs... People still don't know about
Fast Fire Bird's Fire Slide... I think people even just figured out about F-throw to Falco Phantasm which isn't a true combo; it's just a neat gimp. It's like the buffs to Falco introduced Falco as a DLC character in Smash 4... Reflector Void also reflects physical projectiles like Dr. Mario's Pills, but it'll void Mario's Fireballs which are energy-based.
My rundown would be this: Blaster = Burst Blaster = Explosive Blaster. They're all dependent on MUs and preference like Fox's. Blaster's your default, can stun, can gimp option that has stupid end lag when you compare Luigi and Sheik's projectiles, Burst Blaster is there if you just want to tack on damage and have less end lag, but it won't stun, and Explosive Blaster is there if you want another edgeguard option and something similar to Sheik's Gravity Grenade - if you hit the back of the blast, it'll send the opponent towards you allowing Falco to Side Smash, grab, etc.
Falco Phantasm = Falco Phase >=? Falco Charge. Falco Phantasm soft spikes, is a burst movement, and it travels the furthest of the three at 1/2 of FD. The only issue? A FUBAR'd hitbox that lets Falco get hit during the move and hitting in front of him and the end lag pretty much makes Falco a sitting pheasant. Nothing much to say here. Falco Phase is literally an long roll, but I think it travels faster and has less startup than Falco Phantasm. If you don't care for Falco Phantasm and just want a safe recovery, then use this, but make sure to not land onto the stage since Falco will suffer from end lag. Falco Phase also travels slightly less than Falco Phantasm - about 1/3 of FD. Falco Charge is underwhelming because the sour-spot is really weak, it can hit with the sour-spot at point-blank, the sweet-spot's not strong either, and it travels like 1/4 of FD. There's like nothing great as now about it. If it had super armor, lower startup, or was stronger, then sure, it could be a ranged Side Smash which it is, but the sour-spot makes it seem like a pathetic version of Captain Falcon's sour-spot Knee or Zelda's sour-spot Lightning Kick.
Fire Bird >= Fast Fire Bird > Distant Fire Bird. First off, Falco goes deep enough where most characters can't with his jump, wall jump, and Fire Bird. Fire Bird is just *** compared to Fire Fox and Fire Wolf - of all the things to not make like Wolf's -, but compared to Distant Fire Bird, default Fire Bird is just safer. Why? Fire Bird only travels about a 1/3 of Final Destination, charges slow like Fire Fox, but it travels fairly quickly. It still sucks for killing and the fact it doesn't have a strong hit at all even with the last hit makes it have like no priority. Distant Fire Bird travels half of Final Destination - it travels less than Fox's default Fire Fox -, but charges even slower, travels slower, and it still has no priority. The fact people still use Fire Bird/Fox right next to ledge is something that's going to be more punishable when Distant Fire Bird charges slower. It's slow travel speed would make timing spikes and stage spikes easier. The reasons people use Distant Fire Bird is that it "makes Falco's recovery better" and "let's him edgeguard better". Really? How does it make his recovery better? If it's just distance, then that's not anything when you have slower charge time and slower travel speed. Little Mac's Rising Uppercut travels almost nowhere mid-air, but it's really safe if it so much as touches you. Edgeguarding, well, Falco doesn't even need to go far to edgeguard since most people can't go far.
Between launching at frame 44 with Fire Bird for an already crappy move in general that travels 1/3 of FD with launching at frame 52 with a slower moving version of a crappy move that covers 1/2 of FD now, I'd rather recover a bit closer with a faster moving recovery option. Oh, and Distant Fire Bird doesn't have a hitbox when it's charging. It's like Melee's Fire Bird if it traveled further, but slower.
Fast Fire Bird depends on if you are willing to sacrifice a little of default Fire Bird's distance for almost no charge time, faster travel speed, and giving Falco another burst movement. Coupled with Falco Phantasm or Falco Phase, Falco would have 2 burst movements and one of them can travel in several directions. Launching at frame 13 - it has 6 frames less startup than Falco Phantasm -, traveling slightly less than default Fire Bird in the air - on the ground, Falco slides, but you can shorten it by holding down -, and acting as burst movement pretty much makes this a safer recovery option that Falco can use to chase opponents on the ground. On stages with walls, Falco can just wall jump to make the difference of default Fire Bird. The startup does make it difficult to control and Falco will shoot in a direction which could lead to SDs.
Reflector = Reflector Void > Accele-Reflector. Reflector is a fast spacing tool that you need to hit or else since the end lag is pretty long. Use it for MUs where there's lots of projectiles and useful projectiles to reflect back or against faster characters. Reflector Void coming out at frame 13 might not work against say, Sonic who is a living projectile, but whatever. Against Ganondorf, Shulk, or Mario? Sure, go ahead. Reflector Void is essentially a slower version of Melee Reflector, but with more horizontal range. It'll kill if you're high enough and that's no problem for Falco. It's another launcher and kill move for Falco. Accele-Reflector is kind of like Wolf's Reflector where it speeds up projectiles, but it's not safe like Wolf's. It has the same end lag as default Reflector, but does 2%, has little to no knockback, only reflects when sent out, and it's 4 frames slower. It's just not a safe option when Reflector comes out faster and can be used for poking and spacing.
