OMG I'm an idiot. This whole time I've been having trouble locking down the Alioune combo because the second H into magnetic blast was a tough link for me. I'd only get it about 40% of the time. What I was doing was 2H, jH adf jH xx Magnetic Blast L, land, jH adf Magnetic Blast L, 2H...
It works for sure, but as it turns out, this whole time I wasn't supposed to be doing the second air dash at all. I assumed that I'd go up to high if I didn't cancel my upward movement with the air dash, but I forgot that I'm only normal jumping and I'm already on the way down anyway.
So now the link is stupid easy compared to before, and I feel like an asshole.
It's like all the time I spent learning one frame links in SSF4 and then someone showed me how to plink.
