I don't know if this is new or old but I've found something I like to call dash-canceling. I can't explain it very well but here goes. it's a tech where you're able to cancel your dash so you can carry your dash momentum into another move like grab. Also if you do a dash cancel then grab, instead of doing a dash grab it does a sliding standing grab. How to do it: Move your stick forward to dash, then move it to the down forward angle then do the move that you want to do. (Grab,d-tilt,low angle f-tilt,f-smash, etc.) Not every character can do this and everyone has different lengths for their sliding grab. This is very useful for characters like Luigi and Captain Falcon. Sorry if this is old.
