Thank you for your questions
6. Are all cards, just digital cards, no physical cards?
Right now they are only digital
I think EDS should print physical cards you can buy. I think it will be both a revenue stream, will help immensely with communication and interest level, and could be an additional collectors item as well. My suggestion is that the card have a printable square for QR code that has proof of ownership.
I spent a lot of time on the poloniex chat room trying my best to answer lots of basic questions about BCY, SOG, and EDS
Not sure if you work for EDS but here are some of the common themes and not so common ideas:
1. The counterparty, bcy bitcoin, blockchain, relationship is confusing to me and most people. I seem to get most of it now, but this was a barrier to entry for me and others. I think SOG will do well to provide services that completely hide the crypto complexity. I see a new wallet came out specifically for SOG, which is awesome the team is already on this.

3. A common response is "so there is no physical card???", see my comment above. While not necessary, a physical card that has my QR code on it would be cool. I am curious, it seems there is a permanent colored coin marker for each coin somewhere in counterparty techno universe, so regardless of how many time a coin is sold, there is always the same color coin QR code marker? If so my physical card could be forever linked to the digital asset???, which would be way cool and would likely increase immensely the value of my card I own. Of course I would want to own the physical card AND the digital one.
4. There is an idea on the chat room that the game that is coming out has to be successful for BCY and cards to have value. While this intuitively makes sense, it is probably not exactly correct. Especially, if you can tie the coin to a physical card, because then it builds on its secondary value which is a collectible.
5. Also, the cards are inputs to game play, whether it is your current mobile game or an actual card game, there could be many games that are built on top of the card attributes. Are there any such plans for additional games built on top of the card attributes?
6. It seems the EDS revenue model is to make money in the appstore or android store. For in game purchases EDS is buying 50% back of BCY at market prices? Is there a bot on Poloniex testing this right now. I see odd behavior on Poloniex that could be a test of this buyback feature.
7. Rather than burn them, I think you should do a quarterly dividend and disperse them to addresses with x amount of BCY. Maybe this could be a long-term strategy, I think eventually burning them creates too much deflation, too few coins.
8. If SOG has millions of players isn't the satoshi card going to be too rare with only 1000.... Maybe this is how other card games work.
9. Someone asked if they can play the game and earn bitcoin... that would be a cool marketing feature if you could use shapeshift or something and convert in game credits to bitcoin. People want bitcoin not just bcy
Originally, 1000 were issued but of those, EDS burned 800 leaving only 200 in circulation, but then one SATOSHICARD holder decided to send a small fraction of one card to the burn address, so they made that card which is missing a piece unplayable in the game. 
So yes, SATOSHICARD will be a very rare game asset indeed!
