Every frame missed between the Ledge-Cancel and the Double Jump also increases the waiting time between Double Jump and Waveland.

It’s not Mewtwo specific, but Mewtwo’s fast aerial drift, slow falling speed and low traction all enable easy Ledge-Cancels and long Wavelands, so it’s easy for him to abuse the tech.

The tech is versatile and improves Mewtwo’s platform movement and pressure drastically if executed well, but it’s still largely unexplored.

The application with Neutral Aerial, as demonstrated in the video, leads to strong follow up options, most notably against Floaties. Follow up options include Up Tilt, which sets up further juggling, Forward Air which also sets up further juggling and Forward Tilt to knock the opponent off stage.
