For Aerial Ace, I recall the reason for it being never-miss is that the user just runs around really fast and slashes through all the Pokemon, dispelling the clones and wounding the real one as well (I wouldn't object to slightly decreased damage in this scenario).Okay, like, I keep wondering about this. Does it really make sense for never-miss moves where the reason for the never-missing is like, the user taking the opponent by surprise in some way (e.g. Aerial Ace, Feint Attack) to always hit the right thing when the opponent has clones? For moves that are spread-out or hone on to their opponent in some way it makes sense, but it's always kind of bothered me that for some reason Aerial Ace always happens to pick the right thing to fly at at unavoidable speed, or whatever.
As for Feint Attack, it was flavoured as the user going into a parallel dark realm or something where living creatures are much more obvious so the user could discern the real Pokemon easily. With the spelling change, though, I was thinking we might want to overhaul the flavour, so what I just said might be moot.
