S2J (an abbreviation for Smoke2Jointz) is a Melee Captain Falcon professional who is considered to be the one of the best Falcon players in the world, along with Wizzrobe, Gahtzu, and n0ne. He is currently ranked 2nd on the SoCal Melee Power Rankings and 11th on the 2019 MPGR.
Even for a player of his caliber, S2J has an excellent neutral game, using a combination of precise wave-dashing and dash-dancing to perfectly space his attacks. He is also one of the best defensive Falcons with good smash DI and mix-ups with Falcon's otherwise poor recovery. His punish game is notorious among smashers for being able to 0-death with just one combo (usually beginning with a grab), which is known as a Johnny Stock. He is also a read-heavy player.
A major weakness of S2J's game is his poor edgeguarding. While it has been recently getting better, he is still known to make poor decisions and sometimes even self-destructing by just attempting to edgeguard like at Apex 2015 against PPMD and at The Big House 5 against Abate. He also admitted that his mental game could get better if not for having a mindblock against Westballz, Lucky, and SFAT, 3 players who he frequently plays against and loses to for the most part. He said that this is the main reason that he hasn't reached the top 10 spots on the yearly SSBMRank, particularly the 6th-10th spots. Due to his read-heavy playstyle, he also relies on the player's habits, meaning he does better against other players he has played before.
