Is a Calm Mind Meloetta viable or should I run something else?

Calm Mind would be perfectly acceptable on a Meloetta strictly for Aria forme, since it isn't so great on Pirouette forme. So, for a Calm Mind build, I would suggest a build with Calm Mind, alongside 3 coverage moves, which will probably be something along the lines of Psychic, Focus Blast, and Thunderbolt, I guess.

There's always Choice Specs too, but if you're bent on wanting the ability to change moves, then Leftovers for survival or Life Orb for heavier hits would probably be better options. Also, if it turns out that Choice Specs might be your speed, then you'd replace Calm Mind with either another coverage move or Trick.

At least, that's the way I see it.

Thanks! What I've got now is Leftovers, Substitute, Calm Mind, Psyshock, and Focus Blast. I haven't tried it yet, but do you think Substitute could work or just get another coverage move?
