Sure, I don't think we've ever really covered the Luigi matchup around here, but as he's quite top tier it seems important.
Villager vs Luigi
So he spams fireballs and shields on approach, then I assume shield grabs you to nasty combos. Well I'd say get around just in fireball range but summon a gyroid to protect you. I believe it can take two fireballs, but the start-up before it launches also seems to have extra defense, so likely another fireball. You could also pocket one to let the gyroid progress more.
While Luigi hopefully has to deal with a gyroid or two, grow a tree, Luigi won't want to stick around. He may run further away in which case, you keep pushing him and do this again, then he's cornered and has to jump over you.
Now Luigi has some nice vertical distance, but kinda poor aerial movement. He's floaty, so you'll get some chances to slingshot him, push him off stage. You dont wanna be too close as his aerials may only reach if you're close but they do hard damage.
Only things he can do horizontally to you is side-b and hope for a misfire, fireball again, you fastfall a bit and hit him while he's in endlag as he won't stay level to the fireball for long, and I suppose he might cyclone in desperation of landing, which you punish with a meaty down-air.
Now he's off-stage, great, one of Luigi's only weaknesses is his recovery. He may have to side-b which has nice endlag and you can spike, you may also slingshot the side-b and hope to gimp him, but turnips do this too, slingshot if he's just out of range.
And his up-b is very vertical, but I believe clanks with bowling ball, so youd be better off with turnips I think, I dont know, but I believe all turnips have more priority?
And I guess that's it really. That's the gameplan. Push Luigi off stage by beating fireballs slowly but surely, take advantage of his weird movement by consistently pushing your wall at a distance, finish him off offstage.
Luigi's grabs are deadly so you never wanna be that close, you havta be real careful. But I think...just cause Luigi doesn't seem to have the right movement to deal with getting around such a wall like Villager... maybe this is
55:45? Platforms should help, so stages like Battlefield, Smashville, but avoid low ceilings like Halberd and T&C.
