If we dair someone at a percentage where they don't get meteored off the ground, we can actually push them off a ledge into an untechable fall. On battlefield's low plat we can short hop off, pushing them into the untechable fall in the process, and lock them with uair. On astage like fd we can probably push them off into a dair, or force them to grab a ledge and trump them.
On the top platform I know I mentioned using dair out of uthrow at low percents, well nair two seems more efficient at locking(or forcing untechable falls) than dair and uair on heavies.
I also messed with trumps, characters that pop too high into the airto bair I believe we can get a guaranteed dark dive or uair. I think most that we can bair e can also dair, had ahard time effectively testing but I'm pretty sure a character with a low 100 trump height value can be daired, and probably the majority of them under that value. Btw if we miss the dark dive we can still geab the edge, right after you use it hild back so you drift back as soon as possible if you miss. Lastly we might be able to ganoncide samus out of a trump, if so though it'd probably need to be frame perfect.
Thanks to gleed for the trump ideas, he linked me a gif of falcon getting daired out of a trump. So our options are bair, uair, dark dive, and dair.
Thanks again to gleed for linking me this
