idk if it's much but I'll share some input in here.
Against Falco, Spaced Zairs are your best friend, though really I'm not sure if it's the Falco's I face, but don't be scared by his Reflector. Simply because Falco CAN reflect your projectiles doesn't neccesarily tell you to not use any at all, infact what I love to do vs. Falco when I'm in CGing percent is to projectile spam the hell out of them. This puts the falco in an awkward spot, because this neccesitates his use for a reflector when instead he would really like to get in there and do damage with that CG or chainspike. Similar to how Snake's like to damage themselves with explosives so that the Falco doesn't chainspike for the easy gimp, This is how the projectile spam applies here.
Past CG percent I usually like to get 'just' out of range of his reflector, and if used to ward off proceed with Airdodge -> Zair -> and follow up at close range.
As mentioned before do whatever you can to get the falco off stage. Dsmash gimps are... ideal, but no Falco is going to really be 'that' close for you to accopmlish this. The ideal way to get Falco offstage is throws if you're able to get a grab in. If Falco is on ledge-level with the stage, proceed to throw rangs, shoot arrows, anything you can do to stop the phantasm and force him to use that Fire... Bird? yeah. Once you get him in the situation where he has to use fire bird, stage spiking is an easy task. simply run off and Bair. If the falco's not recovering directly up, a simple ledge grab works since Falco has AWFUL Diagonal recovery.
As mentioned his Chainspike isn't too much to worry about, but most falcos know how to gimp afterwards which brings Camping until that is no longer of concern.
Falco's Lasers > TL's like... everything. Safest approach is with airdodges -> Zair. Do NOT Let the Falco get anywhere near what would be long range. He has so many options at that point that TL just won't overcome until the Falco makes a mistake. At long range Falco WILL use that reflector on top of Phantasms and Lazers. It's absolutely nightmareish to play a defensive game vs. this character. Aggressive but careful play is what this matchup requires.
I would most definately ban Japes against any Falco user in this situation, but that's just me.
I hope this helps a bit. Might be just repeating what people have said. Right now I'm replaying my bouts with Kismet to the best of my ability, and reviewing what I did right and wrong, but it's pretty hard replaying something from a month ago.
