So I recently stumbled across these XY promos and have honestly, really been intrigued by these cards. I have looked up the limited information on these and it seems to be very vague as to how this event took place. Most of what I see is just a broad date range of a month for participation awards. The 2016 Karen Gym Night Battle card said it was given out over a month from August to that September. The All night party 2015 promo seemed to be given out for one day on June 17th.
I was wondering if anyone could help answer how these were distributed?
Was there any prize cards for these unique events?
Since there seems to be a slight naming difference of Night party versus Battle, along with the span of a few years, does anyone have a complete list of these Japanese promos I can reference?
Any information regarding these promos is much appreciated!
