What about unsold cards?  Aren't they supposed to get burned as well when not sold.  Is EDS the big whale for cards?  See for example Age of Rust.  They burn any card unsold.  Makes them really rare and it creates more trust on the side of the collector and player.
How can the market decide what price a certain card is when a big chunk of the cards is withheld by the issuer and can be dumped on the market at will any time?
I believe that the Satoshicard was the only card burned.  But let me know if I am wrong.
