Heh yeah. I'm thoroughly impressed by how amazing FairyMag teams are in the current meta, it's pretty much just like DragMag last generation, except even better in my opinion. So I decided, why not combine a Fairy spam core of M-Altaria and Azumarill with a FairyMag archetype? After that I added a mandatory Rocker, a mandatory Defogger, and a Talonflame to fill a few holes, and the result has been pretty impressive so far.
On a side note, your new challenge features BL Pokemon, I just made a team with a BL Pokemon on it, and your banner has an Azelf on it. Coincidence????
... Yeah, probably.
