I got the Xerneas vs Yveltal Battle Arena decks and am planning to get two Red Genesect Collections too. Fairy works well with Psychic, but you don't get much in the collection so you'll probably be better off just making it a pure Fairy deck using the Trainer cards from both the Xerneas and Genesect decks.
