Do you plan to publish the probabilities involved with getting an epic or legendary? Are there any limitations you're thinking about in terms of how many booster packs will be created via market forces (payment) or by you? As this post demonstrates, you're creating a separate economy of value and being able to create 50 booster packs as a reward with a couple key strokes introduces some interesting concerns about the scarcity (or perceived scarcity) of the cards themselves.
I'm really excited about the potential here, but without the game dynamics being known or the scarcity of the cards involved, it's hard to know how it will turn out in the long run. Part of me wonders if it will be another example of whoever pays the most money (or has access to the special key strokes), might dominate the game play. I'd love to see a card explorer of some kind because this stuff is on the blockchain so there could be transparency like never before, up to and including the transparent probabilities and scarcity of various card types. Promotional giveaways like this are great, but (IMO) they should be highlighted as anomalies and demonstrated on the blockchain so that all cards are accounted for via payments or via direct creation by the steemmonsters in a way the community supports (such as contests like this which add value to everyone).
Either way, keep it up and keep innovating. I'm really stoked about this project.
