Here is how I feel about every match-up with a guess or two of the general matchup.
(+2) pretty easy
(+2, +1)
(+1) in our favor
(+1, 0)
(0) neutral
(-1, 0)
(-1) in their favor
(-1, -2
(-2) Pretty miserable
Match-ups with * mean not a lot of experience personally.


(0): They are all heavy which makes it easy to combo but they also can outrange and get low% kills.

(0, -1): His weight gets you easy combos but can combo luigi right back and hard.

(0)*: Haven't played too much of the matchup but he reminds me of Bowser, DK, Ganon

(-1): Bananas, if placed correctly, can ruin all of your ground game(which is most of Luigi's game).

(+1, 0): Combos on him are super easy and he can't combo you easily. Lasers suck though.

: Shine Spike still hurts in this game and U-smash kills super easy

(0)*: This is the only matchup I haven't really played, ever.

(-1, -2): It is really easy for him to outrange us and he kills early. Also he can keep us from coming back with Fair.

(0): It is easy to combo Ivy but Ivy can space us out pretty good.

(0): We can out-space Jiggly, just be patient.

(-1, -2): My least favorite matchup. He can crouch cancel everything and out-space you. Spam fireballs.

(-1): Kirby's crouch can almost shut us down,he can gimp us easy, and he has good approach options against us.

(-1): He has a sword and his tether grab can easily negate our approaches. We can combo him easy though.

(+1): It can be tough for him to kill us and combos are fairly easy.

(+1, 0): Combos are super easy and it is hard for him to approach. His combos are deadly though.

(-5): I hate this matchup, all we do is Nair all day.

(-1): His fireballs shut us down and his smashes come out quick and can stop our approaches.


(-1): They have swords. Luckily comboing them aren't hard and their recovery can be easy to gimp as well.

(-1): Like ^ but except we can punish harder but he can punish harder as well.

(+1): Easily break combos with nair and combos can come easy but don't be aggressive and be weary of Up-throw.

(0): He can out-range at times but it is sometimes hard for G&W to kill us. Fair kills for us are super easy.

(-1): PK fire can shut us down pretty easily. Once we get in though combos come naturally.

(0)*: Pikmin hurt but it is hard for him to get in on us, we can gimp him pretty easy.

(+1, 0): We can hit peach hard and she can't really combo us/ hit us hard.

( -1)*: He reminds me of the mario matchup but faster and it is a little easier for us to get in. Up-Smash hurts tho.

(0, -1): He has a swords, and speedy projectile but his kill options are a little lackluster. Gimping his isn't too hard.

(0): His arms make it sorta easy for him to space us out and he has good approaches.

(-1): Good range and her projectiles are pretty good. It can be hard to land a kill on her too.

(0, -1): It is like the melee matchup except it is a lot easier for us to get back on stage.

(+1, 0): It is hard for both characters to approach but we get harder punishes on snake.

(+1): Cyclone can easily shut him down and we can out-range him easy.

(+1) Reminds me a lot of the Sonic matchup. His smash attacks can easily punish us.

(+1) He is slow, range is mediocre, easy to combo, and super easy to kill off-stage.

(0)*:He has a good combo weight and can not to hard gimp. He has hard punishes though.

(+1, 0)*: Reminds me a lot of the falco matchup.

(+1, 0): We can combo Yoshi easy and gimping isn't too hard. Don't let your guard down though.

(0): We can't combo her but she dies early. She can also punish hard and her fireballs can be shut us down a little.

(-1): She has range, can combo us pretty easy, and her projectile doesn't clank with cyclone(which is hella annoying). Personally one of my least favorite matchups.
In general I feel like Luigi has a lot of neutral match-ups but more match-ups that are unfavorable then favorable. But I he isn't un-viable in the least and winning with him feels really rewarding. Also this list is biased towards me for sure but I do feel this is a somewhat close approximation of current match-ups. Not sure if I should of made a new topic on this or not so I just put it here.
