not sure if this matters or not, but on DL, as falcon vs DK, if you upb DK right under the middle plat, you end up landing exactly on the middle plat, as if you just z-canceled.
Not sure if this has been posted or not in 15 pages but, when in Kirby ditto's and you suicide fgrab with Kirby off the edge of DL, if the Kirby you grabbed jumps at the exact moment that you die (or perhaps right after you die but before they have gone down as well), they'll survive with all jumps and can make it back to the stage. I just did this in Kirby ditto's earlier and the guy I was playing against said "wat .__." and I reacted accordingly. Didn't know you could survive that as I had.
