I'll make a post about the stuff I want to add later.
But first, the stuff I disagree with/comments on your stuff:
Smash G 0 D said:
Aight, first of all, Luigi can combo the hell out of Fox. He's fast, so juggle combos will rack up damage on Luigi HELLA fast. Dsmash at 0% will probably go into Dsmash. You can throw Utilts in there and finish with an aerial. Start combos with Uthrow/Dthrow into turnaround Dsmash or Ftilt or something - it's all basically free damage. You just have to land the starting move!
????
- Luigi's combos on Fox are alright, but I'm pretty sure these characters have better combo games on Fox:
Fox, Falco, Sheik, Marth, Falcon, Doc, ICs, DK at least. Jigglypuff too if you count all the ways she can gimp/rest Fox. Peach, Pikachu, Mario, and Mewtwo are probably tied with Luigi.
- If you dsmash fox at 0 he has frame advantage; it's not gonna lead to another dsmash unless he does nothing.
- throw -> smash combos are bread and butter and pretty effective, but with DI they only set up for techchases and not true combos. At the percents where you are trying to do dsmash -> finisher, if they DI the dsmash it generally won't combo into a finisher.
I think you are exaggerating a LOT when you say "it's basically all free damage". Techchasing is the key to getting big punishes vs. Fox, and techchasing isn't free damage (at least nobody currently has the reaction time to make it so with Luigi).
- utilt is one of the more reliable ways to combo at mid percents, provided you control your wavedash length so you don't overshoot them while chasing their DI.
Also, at 0%, you might as well learn the CG with Uthrow. Which turns into a WD CG at above like 30% (see: Ka-M). It's definitely worth learning because it makes FD all the better a CP for Fox. You can finish the CG with Dsmash aerial or something and you'll have a VERY solid combo.
I think mixing in 0-2 uthrow regrabs is very good to do at the low percents (like sub 20) because
A. they might miss the back DI
B. it might throw off their tech timing.
C. uthrow -> usmash is way better at like 10 percent than 0 percent.
However, there's a segment around 30% where dash regrab doesn't work anymore and I feel like no Luigi player currently can react fast enough to make chaingrabbing reliable at those percents. Feel free to link me to a video if you think I'm wrong about this, but I'll have to see it in action consistently before I'm convinced.
I think chaingrabbing is viable above 50 or so, but even then it's pretty hard and I've never seen it reliably done until somewhat higher percents.
Luigi also edgeguards Fox fairly easily.
Again, pretty much all the characters above Luigi on the tier list edgeguard Fox as well or better than him. It's very easy to edgeguard Fox when he has to up b from below the stage line, or from very far out. However, Luigi lacks an extremely strong combo finisher like the knee or tipper, so vs. an opponent with good DI the usual dsmash/throw -> dair combo finish will put them in a position above the stage where they have a lot of options. He also lacks good horizontal aerial mobility and a speedy diagonal up b, so he can't cover options by aggressively edgeguarding offstage (when they are above the horizontal line) like falcon/mario/marth can.
You usually have to make at least a 50/50 read to edgeguard successfully in these cases.
You can hang on the ledge and drop Bair almost any sort of recovery attempt he pulls out when he's below the edge line (imaginary horizontal line coming from the ledge).
I agree with this. If he has to up b below the stage line and not far from the edge horizontally, ALWAYS go down there and kill him. Depending on the situation, use fair/dair/bair.
You can mix up edgeguarding against Fox a LOT. Example: lower tilted Ftilt to cancel phantasm, drop down and Bair him into the stage for a stage spike. I find this easier to land on Battlefield, but I've seen it done on Dreamland, so it's easily done on pretty much any stage if you read the phantasm.
for some reason the downward angle ftilt seems to let the grab the edge even if they get hit by it sometimes. I don't really know how it works. Also, going for stagespikes is pretty bad if you have other alternatives, imo. A lot of players expect shenanigans when they are recovering and tech by habit. In the setup you described, you have time to grab the edge - > drop down with a dair to hit them away from the stage hopefully.
Fair/Dair/Bair will all beat Fox's recovery moves. Once you get Fox off the stage with Bairs/Ftilt/Throws, it should be easy pie.
Again, biggg oversimplification. Fox actually has a ton of recovery options. Obviously Luigi can edgeguard Fox, but in my mind a character edgeguards another character well if he can cover the options in most common situations without having to make a read. This isn't the case for Luigi/Fox imo. If someone can describe to me a method to cover all/most of the various firefox angles and illusion heights, as well as shortened illusion sweetspots, I'd be happy to be disproven. In every situation I'm sure Luigi can bring his success rate to at least 50/50 if he executes very well, but we have to do a lot better than that if we want to say that Luigi edgeguards Fox "easily".
Your hits will be much stronger on Fox then his are on you, so you have to use this to your advantage. Fox can't combo nearly as well as Luigi can combo Fox.
I think Fox's combo/punishment game on Luigi is pretty much just as good as Luigi's is on Fox. Maybe if Luigi is godly at ccing and smash DIing on reaction this isn't the case, but Fox has a lot more stuff on Luigi than most people realize.
What should Luigi watch out for?:
I need confirmation on this, but is it possible to CC Fox's Nair and attack him with Dsmash or something before he shines you? I feel like Nair -> Shine isn't that dangerous for Fox to try.
Luigi can definitely CC/ASDI down dsmash, and I think it's one of his essential defenses in the matchup so that Fox doesn't just walk all over you for free with nair pressure. You can't rely on it too much, though. Like always, Fox can mix in drills if you are just CC spamming.
Also, if the fox is technical and fastfall/l cancels quickly, then often ASDI down downsmash won't work because you don't get the reduced stun. It's still really important to ASDI down every nair that you can, though, because if he actually knocks you into the air then you are in trouble.
What stage should Luigi ban?:
Fortunately, there aren't any really bad stages vs Fox. It depends on your preference and how the Fox plays.
Rainbow Cruise is a semi-popular counterpick vs Luigi. I don't honestly know how the matchup plays out there, though.
I think Kongo Jungle 64 allows Fox to win by timing you out if he really wants to, but almost nobody tries to do this.
The worst might be Battlefield because of the crappy edges. They hurt Fox, but it pretty much demolishes any sort of recovery you could hope for besides UpB and high recoveries.
I already said my bit on this; I think Battlefield is a fine stage vs. Fox, unless you know that the Fox won't edgeguard you properly and will let you recover on other stages.
Anything else you would like to add:
From 0%: Uthrow -> [Turn-around] Dsmash -> (if they miss the tech) Jab reset -> Shoryuken!
0%-52%
It isn't guaranteed, but it works.
