So I found something in training mode the other day that I think could have quite a few uses. If you flip kick into a wall, and you mash jump as soon as you get into contact with the wall, you can do a second boost kick. You can only do this if you haven't pressed b for the strong hit of boost kick. I don't have a capture card so I don't have any footage, but I find it fairly simple to pull off. I don't know if this is common knowledge already, but I believe it could be extremely useful when recovering or for edgeguarding. If anyone has a capture card please post some footage. Thanks!
