Falco/Sheik.
I started off playing Sheik when I started but ended up picking up Falco just for some issues with playing certain Fox styles but eventually just ended up liking Falco's combo game more and Sheik ended up becoming my secondary for just the Marth matchup as I enjoy it better than playing Falco into Marth.
Followed the game for a while but only ever tried playing the game in the past 4 years. I've attended big tournaments near me such as CEOs here and there and Paragon Orlando 2015 and didn't make it far but its still a good time since friendlies are always going on and just hanging out with some cool players.
With today's netplay scene its very easy to find someone with decent ping to become a practice buddy and just grind together. You don't HAVE to go to a local to play the game and practice due to this but locals you can meet some real cool peeps that want to have fun with the game too.
Getting into the game is fun and just learning the mechanics but don't jump into the game trying to be the fanciest player in the world trying to perform some technical stuff like multishines and all that won't be too helpful when learning the basic things like knowing how to move around with your character and neutral/punish game for said character and obviously directional influence (D.I) should come first and the rest comes with it.
