Just to throw a spanner in works, the VGC Nationals in 2014 in Manchester distributed a Mamoswine that was distributed via a laptop program. I saw the attendant click a program when I asked when it was going to be distributed. It ran twice that day, from 10am-11am and then 3pm-4pm.
I actually have the Wondercard still unclaimed in both X and Y. I don't have a means of extracting them though to determine if there is any difference.
