I admire that you've decentralized features of the game even further. As it currently exists, of course. It will be interesting to see how third-party sites will now exploit this new capability of combining and trading cards. You've just opened up the opportunity for a marketplace on here, independent of the official steemmonsters website. Thanks for the technical details!
I debated commenting because it would simply be a spammy comment since I'm not very techy. However, I decided to leave my short comment afterall. :)
