Usually at low percentages I will attempt a Dash Attack > U-Tilt > U-Smash > F/U/N-Air. (Fun air? Seems legit.)
At higher percentages I do Dash Attack > U-Tilt > F/D-Smash. But it seems this is really easy to DI out of.
Sometimes I will do Dash Attack > D-Tilt > F-Smash but mostly I don't rely on D-Tilt.
The site shows Dash Attack > U-Tilt(?) > U-Smash > F-Air > Side-B, but I've only been able to successfully do that offline.
