Again, I hate comparing Dynamax and Tera because they are extremely different. In fact of was in favor of the Dynamax ban in the past. But the big point I was trying to make with the Acrobatics Salazzle comment was simple: With Dynamax you couldn't ban one or two mons to balance out the tier because something would always take it's place. As you made mention, Gyarados , Togekiss, and Corv were all incredible sweeper threats due to access to powerful Max Airstreams. If all 3 were banned, 3 new Airstream sweepers could easily take their place.
