Collected these as I was opening a large amount of Prizm through retail options collecting the various parallels (since sold). While I was more focussed on Stanley Cup auto sets back then, I still held on to these, just didn't chase the missing ones. Still quite a few more to get as I happen across them, but like most lower end cards I won't be actively searching so much as picking these up when the price is right and there is no shipping to be paid.
