As soon as I saw this I started to play around with it because it was so awesome. However, I found out the locks stop working around 30-40% for most characters (or at least the ones i was trying it on). That in itself is going to limit setups to the 0-15% range for us to get much benefit out of it, if at all. With this limiting factor and the fact that we don't really have any set-ups other than b-throw(if for some reason they don't airdodge, attack, or maybe even jump?) means that I don't think we'll really have a use for this technique.
I don't want to denounce this find at all though because I find it simply amazing. There is still room to be quite useful if we find a good set-up.
I haven't tested this on a human player, but assuming we can even get the throw when they are around 0-15% (maybe with a glide toss->throw) it can lead to a significant amount of damage and for some chars a 0 to death if spaced properly so they get dsmashed at the end of the stage as shown in the video. However, as I said before this is only if they don't seem to do anything after that throw. It's a long shot, but I suggest to at least try it for one stock of your opponents stocks, because the payoff is very large if they aren't paying attention.
It doesn't work with tripped opponents, which is unfortunate. It also seems easiest to do on larger characters (d3, snake, bowser).
*edit*
I tested the plasma wire set-up and unfortunately it doesn't work. If at low percents the opponent lands on their feet, and at high percents f-tilt won't lock. It does work if you hit with just the 1st and 2nd hit, if they don't push any buttons and land on the ground. Which is going to be unlikely.
