In past years, there have been many great strategies that have been (not the tier) over used in VGC. For example, last year. All of those thundorus with acrobatics. That was insane.
Now that the regionals have begun, what kind of Pokemon are the new acrobatics thundorus of the world?
I am aware that Mega Charizard Y, Mega Mawile, Gale Wings Talonflame, and as always, Rotom, are four Pokemon that have showed up a lot already. Are there any other noticeable strategies that have risen, and if there are any, what are good counters for them.
