Misty was only in Mastermind because it was a 10th anniversary special. Even ignoring the whole VA change fiasco, the whole special itself was poorly written and felt like bad fanfiction. All we saw Misty do is use her
Staryu against a virtual reality
Aggron and lose (naturally), and then she just falls off a cliff with Ash forgetting about her till the tail-end, (naturalyl).
What bothered me is how out of character Misty was. Calling Ash, "her rival," when she NEVER called him that in any previous episode, and then trying to play up some grudge between her and May...like WTF? I like to think of Mastermind as non-canon, I wish it never happened.
