So I finally click this thread to see what this bdacus is and WOW, ive been doing this **** since i dunno, last year lol .
I recall seeing Japanese Falco (bombsoldier?) do this to a MK on Smashville and wonder how the hell he got sooo much distance with his dacus.
After learning Sheik and her DACUS, i realized that it works for Falco and , Snake, and it gives Fox a Dacus, Fox timing is the hardest to do.
I should have made a thread ages ago, sorry guys.
Like people have already stated, D throw to Dacus is great tool for those who dont expect it.
Edit: I didnt read the entire thread, but the easiest way to do it is to change R to Attack, then use that in place of the shorter Dacus. Im not calling it bdacus, its still just a dacus with different input
