A bit old. people have been doin it from almost the start. Its a good trap but people can tech roll out of it or jump over the net when timed right, or wake up teleport if they have one. Still tho i do it all the time if i don't have meter but sometimes follow it with a close or far bomb before or instead of a net to keep it unpredictable.

Another good one I've had a lot of success with is Net, njp, b2, medium bomb, dash, 2,2 and then combo of choice once the bomb pops them up in the air. They can of course wake up attack or sometimes jump out but its surprising how many higher level players fall for it or can't do their wake up attack in time.
