I ran into a Mesprit set today that I thought was somewhat problematic, which was Choice Scarf Mesprit with Psychic/Trick/Calm Mind/Substitute. There's no proof of that in the replay as I only used one move with it the entire match (shocker!), but I'll include it below anyways. I suppose in theory it technically has Trick, so it's not like an objectively dumb thing, but I still think it's pretty bad and should be fixed. Even ensuring Choice'd sets have two functioning attacks would go a long way. (Psychic/2nd Attack/Trick/Sub is probably ok, for example)

Also about the Hariyama set I posted earlier--no I don't know its other moves. The only one I know is Helping Hand, which is the only other thing it did in the game.
