YS, FoD, DL64, and Pc stadium are all in falco's favor. marth wins on battlefield and fd.
reasons why falco is better than marth.
falco's shield pressure is stupidly good, like honestly i will list out options here since i've got nothing better to do right now.
Falco can approach with low lasers, destroying the idea of dash attack.
Falco can approach with one close laser to put marth in his shield for a grab. the only way a marth can do anything about this is to cc all the lasers, DI down and away for a counter, but even then if the falco has good spacing a dash dance can simply punish marth badly right there and the counter will be avoided(if we are playing perfect).
falco plays the platforms better than marth, has auto combos regardless of DI. By this i mean at low percents marth in reality cannot escape a pillar. honestly falco vs marth they both have kinda the same objective, to get you above them because both of them can **** each other if they are below, although falco does have a much better down air to recover from juggling combos.
Falcos lasers absolutely ruin marth, like honestly, i know Mo the laser trick with marth but even then if a falco reacts fast enough/times his attacks, jumping and hoping to god the fair comes out before falco hits you is unlikely.
This is why falco beats marth in the matchup, Dekline is king at it. Crouch cancelling. Falco can seriously take a tipped fair, or down air sometimes cc down and away from marth and hit marth with an fsmash, its stupid.
http://www.youtube.com/watch?v=Qna80MbcAAc at 1:12, m2k doesn't space his bair well, shiz ccs to fsmash, this is an example of how gay ccing can be in the matchup.
Marth against a good falco who places lasers well is FORCED to play defense, if you try to be aggressive against a falco who lasers well, he will simply camp you, laser you, close the gap use laser lag and get you in a combo.
Marth can only do so much, most of the time you will find all marth players sitting in there shield against a falco hoping to wavedash away from a pillar to get a tipped/untipped fsmash, or they will hope the falco will dash attack through to jump OoS bair. Shield grabs are possible but unreliably difficult to get off because it is based on your shield DI, the spacing of the falco's shine, and whether or not you grab on the immediate 2-4 frames its available. Or you can grab a falco who sucks at shffling dair shine.
Even so, if a falco does pillar your shield, its a bad mistake on falcos part. a Falco can simply jc grab out of the shine and up throw you to bair, dair, uair, or he can put you towards the edge of the stage with an fthrow. Falco can also Pillar your shield but rather than shine your shield, He DI's away, you go for a grab and he fsmashes your face.
My hopes when playing a falco are to get grabs, tech chase, space well, hope for a dash attack, and put them on platforms. Most of all if i can get them on the edge they are done for. I also powershield lasers to mess up falcos composure.
Falco is the 2nd best character in the game, and BEST character against people who don't know the matchup.
