The team should be releasing an new set of rewards cards before too long. We've already tried to have votes to address unlocking or "blockchainizing" the current ones that failed. We just passed a proposal to limit the bot farms that don't own anything from just renting for ROI rewards farming. I'd like to see us get away from soulbound reward cards in the future but that's kind of a team decision at this point. There's also already planned utility for the soulbound cards to be usable on land and hopefully unlocked at some point with a land resource. I guess we'll see.
