Overview
Meta Knight does a quick horizontal slash below him, doing 7%-9% damage and hits on frame 4. Like his up aerial, the move has extremely little start-up lag but has a bit more ending lag but has very little regardless, making this move hard to punish. The move can be often used by players to dair camp to space his distance between his opponents in the air. With its semi-spike trajectory and decent knockback, it is one of the best edgeguarding moves in the game. It does great against opponents with poor horizontal recovery.
Overall, an excellent move that is reliable and not difficult to use in Meta Knight's metagame.
