I am not personally into Splinter lands enough to know anything significant about it, but my boss @bozz explained it all to me and you are insane!!

Congratulations on the airdrops, you are gonna have quite the powerhouse of max level cards from the free 88.

Am I right in saying you only opened a small fraction of what you have? Good luck with the huge task of sifting through and upgrading all of the cards, going to be a fun time.
