Think FFG will do anything with the Proof of Purchase. Would be cool if they did, even if it was something like trade them in for acrylic tokens or something of the like.

Remember the good old days when you could trade in your points from GIJoes for something. That would be sweet

I was thinking this the other night.

Alternate card art only available through that program. Perhaps even a trade in for specific upgrade cards. It would require a fair amount of work on their part unless they only did something like that at Cons they were attending so they didn't have to bother dealing with mail etc.
