@shulix- yuh kinda have to use zair as you start to come down, most or all the time shorter characters wont get hit by both parts of the zair if there grounded. its just fact, nothing your doing wrong. just keep in mind that zair is good against mk's nado every so often, as well as his glide attack. as for g+w and kirby, when they are crouching, you can pretty much 4get about zair and think of spamming. most shorter characters dont have that great of a projectile game, cept olimar. fame and watch is outcamped by link easily, but will kill you very easily whether it be gimp or upsmash. remember your tether option with his dsmash out of dthrow. mk, bombs and zair work semi decent against nado, if your opponent is lame enough to use it. if they glide in, zair or run behind them. other then that zair is some times just a last ditch effort against mk when you know your going to die and hes coming out to make extra sure you dont recover, zair into upb will dmg him a bit b4 you fall. fox, isnt the best character to zair because of his speed and ultra fast attacks and combos as well as broken as hell usmash. tend to stay middle stage and you can zair if hes on a ledge, possibally knocking him off into a jab lock. maybe? usually when fox recovers with forward b, he isnt ground level, and can be zaired or bombed or even galed if you got the timing. other then that jabcancel into zair works 35% of the time. and thats what zair can do against fox, mk and g+w.
