Mythra goes forwards and slashes horizontally. This move sends out so it can be used to begin techchases, edgeguards, or begin corner pressure. Dash Attack is also very good for catching landings as Mythra low profiles during the attack, and her burst range is massive due to her initial dash speed & length.
