Didn't someone cut with the Rainbow Force deck?
I love Xerneas and it's awesome to see someone trying to make the Rainbow Force version work. I tried a Pokemon-EX version using Hoopa-EX to fetch them all out. It was more of a toolbox version instead of a deck that focused on Xerneas, but I like the idea of Brigette and low little girly basics instead of nightmarchsalivates.dek.
I, too, would have liked to read more about Fairy hype. And how can you have a Xerneas article without even mentioning Mega Gardevoir, literally Xerneas's best friend? Kinda surprised to see you actually ran Mega Diancie to varying success. Mega Pokemon with no Spirit Link is cancer.
