[RATE MY TEAM] Is this a good moveset for a Latias?

I think it depends on the team you have and what you need to outspeed and what you need to tank hits from.

I'm not a big fan of mono Dragon attacking move with all these fairies running around nowadays. Psychic/Psyshock might be better here. But once again it all depends on the team and even the tier you are in. Best of luck. ^^
