Eh a lot of these aren't practical as of now even. Most of them involve being the right distance and angle from a wall. Then there's the problem of moves randomly whiffing if you're two degrees off or the opponent is facing the wrong way combined with the likelihood of landing the move you need at that angle. Then there's the fact some require 200 percent meter. "Practical" Is not the word I'd use to describe this vid, it's more like a "dream combo showcase".
