Regarding Team 1, I don't see much use in Defog. Hazard removal isn't that great in 3v3 (prevention is preferred), and you're not running any Sash mons or Volcarona on that team so you're not exactly weak to the hazard. Sticking with that nature; I'd consider Iron Head to cheese Mimikyu with para flinching. Especially since Mimikyu is one of your uglier matchups with that team.
o the first pokepaste was just me throwing out ideas that I used on previous teams and on one team I had defog silvally but yeah when I did have it on one of my teams, I'd rarely used defog so if I decide to use silvally on my final team, ill definitely look into replacing it with either iron head or rock slide to play the paraflinch game
