Ill give a bit of insight for both falco, ROB, and GaW
I haven't lost to many falcos with some of them being very good
Luigi's Strengths
No Laser’s hit Luigi…..Crawl goes under even silent laser’s
Better killing moves that falco
Not that easy to chain grab against Falco
Down b helps approach
Can “combo” easily with up tilt and down throw combos
Do NOT spam fireballs
Down air and back air helps with gimping
Up B combos moderately easy
For stages, I recommend any type of curved stage that does not have walls such as Lylat Cruise. I do NOT recommend platform stages such as Battlefield due to spacing or wall stages such as Corneria. Play stages that aren’t that big and either ban FD or Battlefield. I personally prefer banning battlefield due to platforms and It is easier to gimp Falco.
Falco's Strengths
Chain grab but harder to do vs. Luigi
Down B actually helps vs. Luigi due to Luigi’s traction
Aerials
Down air gimps Luigi’s recovery
Playing defensively/campy is easy for Falco
FD and Battlefield are both good counters
Consensus:
Overall this matchup to me is either 55-45 or 60-40 Luigi, it is way too difficult for Falco to kill Luigi. Predict his recovery and predict his recovery. Just be careful and you will be fine.
Game and Watch: I have played great ones online and somewhat good ones offline, anyway
Luigi’s Strengths
Use Down B sometimes to approach
Down throw will knock Game and Watch to the ground, anticipate tech’s or get up attacks
Up B kills at incredibly low percentages even with DI
Upward Angled and even Downward Angled F-Smash can be used to hamper shield well
Reverse Down Smash is a quick kill
N-air helps
Back air can help
Can overwhelm game and watch’s shield just as well as GaW can overwhelm yours
Final Destination helps, Pick a Large stage because Game and Watch kills way too easily. Platform stages are also great to get out of aerials. Personally, Pick Battlefield or FD. Ban Congo Jungle for CP’s and Yoshi’s for first stage.
Game and Watch’s Strengths
Better recovery easily
Back air, down smash, and f-smash are difficult to be abused
Luigi’s traction helps this because Luigi will move after shielding
Down air goes through many of Luigi’s moves
Can Bucket Fireballs
Smashville, Yoshi’s Island, and any small counterpick. Anything with a low ceiling, I see most of them countering with Congo Jungle and smashville. Ban Battlefield or FD.
Consensus:
Overall, Game and Watch has too much priority and Luigi’s traction really hampers his chances of winning. Down Smash really helps and Up B Combos really help. Don’t Fireball too much. 60-40 Game and Watch and this ratio is not better for GaW because Luigi can kill GaW easily.
Rob: I have played vs. DullRazor online + a whole lot of other R.O.B.’s online or offline. I personally like this matchup
Luigi’s Strengths
Back air vs. Rob’s Recovery
N-Air helps a lot
F-Smash really helps
Reverse down smash = Major Win
Combos with up tilt and n-air
Up B combos = easy to do
Fireballs help with camping rob’s
Down tilt trip combos
Recommended stages: Green Green’s if allowed or Haliberd for CP’s, ban FD because its too large, Smashville is normal, Battlefield is fine if used to matchup,
Rob’s Strengths
Recovery
Glide Toss from Gyro into F-Smash = ****
Rob Laser = epic
F-air into down air gimp
Good moves vs. Luigi’s recovery
N-air
Up Smash > Luigi’s down air
Best stages: Frigate Orpheon, Luigi’s Mansion for CP’s, ban Yoshi’s or unless your R.O.B. is good on platform stages, ban battlefield, use Final if possible for first stage.
Consensus:
I personally recommend spamming back air vs. R.O.B. Try not to approach R.O.B. from above due to Up Smash. Fireball if he runs away and use n-air a lot. Down tilt to trips and down throw combos. F-Smash and Up B combos kill well and its easy to get out of Rob’s down smash and your down smash is great. This match comes down to who can get that last hit. I believe Luigi has a slight advantage because it’s easier for him to combo.
