Vegito dash 236S (check description)
Inputing dash (66 or 6+SD) before certain special moves allow them to keep the dash momentum, mostly to make the move master. With vegito 236S, it allows for a 2H-free air-to-ground if split finger shot is done at the apex of the dash (first example), and allows for a 236H conversion if the move is done at the beginning of the dash.
