we don't know how to get Diancie yet. it's a event pokemon, but the event type hasn't been released yet afaik
i'm hoping it'll be a standard GTS event. though pokebank event is possible as well
*waves arm wildly* MEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE!!!!!!
I actually did notice it the first time I played...
from where is the right pic ?
