Well, I encounter TTar and other Pokémans who have either sand stream or anything that lets them damage my Smears after I've spored them very rarely.
Oh, and lel, I forgot to add in Smeargle classic baton pass ;-; Baton pass/ Spore/ Belly Drum/ Agility.
Though I love using baton pass based teams, I have several sets for Smears.
The following is for when I sweep with Marowak, I can make him extremely bulky and incapable of switching out by adding ingrain and taking out agility. I then put calm mind on Espeon/Blissey (get +6 sp.attk and +6 sp.def( yeah, yeah, sp.attk stop laughing ;_; ) and then pass all the boosts onto Vaporeon and acid armor up to +6, and then pass it over to Marowak.
It works about half of the time, but you get that glowing feeling inside when you succeed and you attempt it again ;-;
Also, that Smeargle set you've stated sounds great :3 I'm gonna try it out in Showdown.
One of my best matches ever:
