Ciao!
I didnt see one, but would you mind making a team around Meloetta-Pirouette? It seems quite good with its overwhelming speed when it transforms, solid STABs in the form of Frustration and various fighting options, it also has different options for the last move like Ice Punch, Knock Off, and U-Turn or even going mixed with Psychic or Shadow Ball so it doesnt necessarily rely on using Relic Song. I don't necessarily think i should post a set or EVs as its generally tailored towards the team (as i have my own team archive and shop, i understand this). You'll be mio eroe if you do this! Feel free to take your time.
