Very start, you rolled in toward him. Don't approach with rolls.
At 1:13, you roll twice to get behind him, please don't roll
At 1:16 you did d-throw -> down b when he was no even close to kill%, use Bair/ Uair/ Nair next time
At 1:24 you did this again ^ =/ Learn when Luigi will kill, if there are no guides, teach yourself
At 1:49 you did d-throw -> bair when he was at 37% when you could have done Dair -> Nair/ Fair -> Uair or Uair -> Uair
You then let him get on for free :l
Please stop rolling/ dodging when he's not in a situation to hit you, if you're on stage below him, you have the advantage, don't be scared =/
Game 2, 24 seconds in is just a bunch of cross up rolls =/
3:22 Lucina hits your shield with Fair. You roll toward her, Jab and then roll away when you could have jabbed Oos
3:33 You are now dead because of a fair string you jumped into, jumping immediately when you're offstage is bad, it is why you died. You are Luigi, you can recover from the blastzone
You try to cross up roll a lot, please stop. Please stop rolling when you miss a move.
3:53 You go for a hard read d-throw -> up b, trying to read the dodge when Bair would have killed Lucina =/ That airdodge read is only good between 65% -> 85%, after that, it's not really worth it.
3:59 You had the trump advantage, could have down smashed. You rolled away... twice, even though getting the read, the roll away twice wasn't necessary
Again, please stop rolling
3:59-4:53 was a bunch of rolls and jabs, and flubbed edgeguards. Not much to say.
4:54 Lucina was at 128%, D-Throw -> Down B would have easily killed, Same as Bair, maybe Nair.. but you went for a dair for maybe getting a flashy spike on stage ? You had the kill and wasted it =/
4:59 You missed a Nair, Down B is a lot easier, especially at this damage
You can argue you got the kill 27 seconds later, but I can argue if you got the kill far earlier, you could have been comboing her for those 27 seconds. And these are the games you won =/
Please use d-throw bair when it will kill, not when it won't =/
7:25 Bair, would have kill but you went for dair.. 3 times and then died
I'm not even going to comment on how you lost your second stock game 3
And then you got stage spiked
That's all I'm watching.
Your recovery needs work, your strings need work, you need to stop rolling, and you need to pick your options better
