If i buy one of these packages, can i freely choose the bundled creature and how to do it when it's time to redeem?
Yes all packages come with a choice of creatures. I believe it will be done via swapbot, so you'd get a diamond asset for the diamond package then you send that asset to a swapbot to select the creature you want.
But this is me speculating. Maybe worth asking the team on Slack.
Thank you it's good to hear that we can freely choose the creatures.
