Before anyone starts saying how they hate Europeans or that they play favorites, from Silvestro himself here
Stephen Silvestro said:How it was explained to me was that they generally take the winners in each age group, unless there is a repeat deck in which case it goes to the lower age group.
They didn't print Sami's deck because there was a flygon in the lower age group.
They didn't prin Khan Le's deck because there was a blissey in the lower age group.
I'm sure that them being European is just a coincidence
