I'm waiting for my daughter who enjoys opening chests and discovering airdrops so I have to wait until tomorrow.

Awww - that is awesome!
I might introduce my daughter to card opening for Rift Watchers perhaps -though the images might scare her, so unsure.

Consider that it took me longer to choose the avatar than to choose the formations of at least 20 battles

This is why I left mine as default :D

I think it would be quite a unique addition to be able to not only create the in-game avatar, but mint it as an official Splinterlands NFT too.
