Sheik is a playable character in the Brawl mod Project M. She has been reverted to her powerful Melee version with some additional minor buffs. She ranks 7th out of 41, at the bottom of the A tier, on the current official tier list. She roughly places the same as her 4th place position in Melee and a significant improvement over her position on the Brawl tier list, where she ranks 25th out of 38.
Sheik falls under the same archetype she did in Melee: a lightweight fastfaller with quick albeit weak attacks made for comboing. Sheik's frame data is among the fastest in the game, with many of her attacks having very little lag, especially her tilts. She also has a great projectile in her Needles which allows her to camp very well. Sheik also has very fast ground movement, which complements her combo game somewhat and allows her to chase down opponents easily. Her fast falling speed also grants her excellent vertical endurance despite her light weight, potentially making her difficult to KO.
Regardless, Sheik still has weaknesses. One of Sheik's biggest flaws is her survivability; being light, she can be easily KOed by horizontal finishers. This is exacerbated by her fast falling speed, slow air speed, and poor recovery move in Vanish, which makes her one of the easiest characters to KO horizontally. Sheik is also very easy to combo due to her fast falling speed and gravity, as well as her light weight causing her to suffer significant hitstun. Despite her near lagless aerials and fast falling speed, Sheik has a poor SHFFL as a result of her very high short hop that does not allow her to use many aerials in one. She also has significant trouble KOing, as she only has three noteworthy KO moves, two of which are very hard to land. Lastly, as she is almost exclusively based on her Melee appearance, she lacks some of the improvements she saw in Brawl such as her superior mobility, forward tilt, faster up throw and her Chain tether.
However, Sheik's strengths generally overpower her flaws and this results in dominant tournament results. Because of the harsher environment where a larger portion of the cast are able to compete at the highest level, however, her successes are decreased compared to Melee.
