SHFFLing is the quickest and least laggy way to perform an aerial attack. By L-canceling an aerial attack out of a short hop, the player can reduce the amount of landing lag their character has and drastically increase their chance of comboing or following up. The technique can be a little tricky to pull off at first, but is essential to a competitive players arsenal. Luckily, Super Smash Academy has a great guide to get beginners SHFFLing like pros in no time.
