No idea if someone found this yet, but the very first hit of UpAir has very little knockback. I have very little idea about how to test this things, but around 100% i got ot to connect on wario and fox into an upsmash for a kill in training mode. Haven't tested DI because I haven't had the time yet.
Could someone with more experience look into this? Looks promising.
