There are some good strategies into making a definately decent Luigi. Some things that were missing were:
- Maniac Wavedashes
- Mind gaming
- Luring
- Fast Falls and L cancel
- Chain Grabs/Throws
- Better aproaches
Maniac Wavedashes: Though it may not sound like much, wavedashing with a Luigi is actually pretty good. Normally Luigi is slowish-normal speed character. With this wavedash technique, you can easily pretend to move fast. Wave dashing can easily help you lead into better approaches such as, "Wavedash ~> Up Smash", "Wavedash ~> Down Smash", "Wavedash ~> Jab ~> Backwards Grab". Wave dashes can help lead to better approaches. I'll explain down the list!
Mind Games: Dash dancing isn't for fun and to look spazzy cool. It's a big part in mind games. Run back and forth, Luigi is either going to charge into with a wave dash linked combo, or run away like a sissy and start camping. You could also dash dance into a better position to start SHFFLing. Luigi is cool because he can double U-air, B-air, F-air, D-Air. This means getting people and by breaking their shields, or at least attempts to break their shields. All of Luigi's aerials can be linked to a N-air. Such as the U-air and then then N-Air etc.
Luring Your Opponent: Turreting is terrible with Luigi. Do not do it unless you're going to link up the fireball attacks with a quick wavedash ~> grab. If you know your opponent likes shuffling, you would like to shield grab. Shield grabbing can lead into more combos or a chain grab. Camping seems to be the best way to Lure your opponents if they are not Foxes or Falcos.
Fast Falls and L Cancel: Just smash downwards after the peak of your jump and press L, R, or Z before you land!
Chain Grabs/Throws: Here is one thing Luigi isn't bad at. It's chain grabbing! Depening on the % of your opponent or how fast they fall, you would chose to use the U-Throw or the D-Throw. If your opponent smashes their DI, your super fast Captain Falcon equivalent wavedash, can help you catch up to your opponent, no problem, and throw them again. Don't forget to press and additional Z or A when you grab for another 1-3 damage!
Better Aproaches: Good aproaches with Luigi:
"Wavedash ~> Up Smash"
"Wavedash ~> Down Smash"
"Wavedash ~> Right Tilt"
"Wavedash ~> Jab ~> Backwards Grab"
"Wavedash ~> SHFFL"
"The amazing down B!!!"
"Dash Dance ~> Dash Attack"- But not reliable and gets predictable
"The amazing Wavedash ~> Up B" - Or maybe not as amazing.....
There are better approaches. Or should I say more?
Try watching videos from Ppa0. He has a Luigi tutor video.
Other than that! Keep trying on getting better!
Until then have fun
