Averagemons, and I second what Pokemon Master Debater says about STABmons and AE, since we as a community have both played, and enjoyed those metas, we should get a ladder for them, but at this point they are not new, and if we pick old favorites, new ideas will not get the chance to shine.
Edit: Don't worry toxicroaker, it's the meta that counts, right? (Although I guess it would be cool to be known for such a great meta averagemons will be, and already is. After a day of playing it, it's already one of my favorites.)
