Tell me what you think. I haven't entered any tournys yet but when i do i'll say how i do.

Looks mostly standard. I approve :p
Fairy looses a lot of power being unable to move energy around in Standard. Trainers look acceptable (the Spirit Link count may be a little excessive), and the Pokemon line looks reliable. I'd recommend trying Xerneas BREAK (SS 82/114) as a secondary attacker.
