First of all, thank you for implementing changes and updates. In particular, I really like the second part where you build a deck under random constraints each time so that you prevent meaningless bots continuously playing with the same deck 24/7.
However, I do not understand the "cooldown" part. I do agree in a general idea, but the way it got implemented does not seem fair.
If you want to prevent "abuse" of card rotating, then you simply put time limitations (say, 1 week) of gifted cards may not be gifted again. If you cannot use a card for a week after buying/receiving it, it will significantly decrease the incentive to buy/trade, which will result in reduced interest.
While I understand that this is right before the end of the 2nd season, I still believe that you should notice users first for the upcoming significant changes.
- self-boting a small amount to get visibility.
Sellers can make sure not to have played the card for the previous week. I imagine a card that cannot be immediately played should demand a discount on a decentralized peer-to-peer marketplace.
PS is this steemmonsters marketplace on the chain such that it's a decentralized exchange?
