I think I know a better way to handle this if EverdreamSoft starts using the new Skeleton API from Shapeshift.io. If players want to buy these cards, they have to use Shapeshift.io's exchange interface called Skeleton on the Spells of Genesis website. This way EverdreamSoft would never have to hold coins or do the exchanging. Players purchase these cards like the "Shibe Doge" USING Dogecoin through this API and it actually goes and buys BitCrystal off the market by selling the Dogecoin first, converting to BTC, then buying BCY.
There, now you can make cards for every coin on the market and help the purchase value of BCY.
How about a "Bringer of Lite" with Litecoin on the logo, or the Darklord of the Dash, Master of Monero maybe? ha. How about a quest to the top of Mt. Gox?
Or was this the plan all along?
