So why can't you just Ftilt/Fsmash him instead?
And I just tried it and they were too far under to get hit
Well if either of you two can get it on video then go for it until then shut up.
It is possible but it won't happen a lot. Most of the time it won't. I mean specific things like that are going to make any move look godly
Backthrough doesn't
combo. So NO you can't F-smash. You can't even back-air if the person knows what's coming. The entire point is that it provides a decent method of eating a 2nd jump and getting them off the stage.
If they jump you get a free hit and probable edgeguard setup. Because
they usually jump in this particular situation. Christ.
And yes, it won't work on fast-fallers. You see when I made that first post I made some apparently poor assumptions about how well you could figure things out on your own.
I don't know what I'm still doing here. It's not like some super secret fantastic technique. I must be a glutton for punishment.
