Sheik is already quite the technical character in Smash 4, with plenty of precise perfect pivot combos and 50/50 setups which can lead into big damage or a kill. However, there is still room for Sheik to become even more technical. The Beefy Smash Doods have outlined just three difficult Sheik techs which are underused in competitive play but have untapped potential. They vary in usefulness, but they all have some utility in battle.
The first is the intangible ledge grab, where Sheik can refresh her ledge intangibility with an aerial Up B. It is somewhat similar to Shino stalling in Super Smash Bros. Melee, where Sheik can continually Up B at the ledge to slow the pace of the match. It is pretty useful, as it is a possible kill option but you need to have some precise aim to regrab the ledge, or else Sheik falls to her death.
The second is instant needle cancelling which allows Sheik players to cancel their momentum out of a dash with their neutral B, before instantly using a jab or tilt attack. To perform this, players must do the opposite of a regular needle cancel by inputting their select attack before tapping the shield button. The timing is super tight but if done correctly, it’s a great way to catch people on the ground.
Finally, the third technique is the defused grenade, where Sheik can pick up and throw the projectile without it exploding. This requires Sheik to take damage just as she begins the attack animation, dropping the grenade and allowing anyone to pick it up. You can also drop the grenade by slipping on Diddy’s banana. It isn’t particularly useful in a match but it can lead to some super situational setups which may catch your opponent off-guard.
