So do you think Winds and Waves will get a new mechanic, bring back an old one or have nothing?

I think we're getting a new one because mechanics were introduced in gen 6 and have been in every mainline since then. But part of me wants to bring back one. Z moves would be cool but probably not. Megas will maybe come back because they were in Gen 7.

I don't want to see terestializtion again tbh or Dynamax.

What do you think?
