Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
In my opinion it definitely has. My personal suggestions for the sample teams are:
Change the rain team into a Manaphy variant, I'd go for either Mob Barley's or Ske's.
Add a semi-stall team, I'd go for Charmflash's (showcases Ditto) or Empo's.
Add a hyper offense team since we used to have one but not anymore. I don't have a specific one in mind but I think the screens Tapu Koko variants are the most viable, maybe featuring Hawlucha and SG Magearna or even Kommo-o.
