Sounds like a cracking game to buy with Covid.
I've never heard of it, seems like a really cool concept but also a concept that would get old very soon, same cards, same upgrades.. you for sure would need some sort of update/dlc in the form of a new deck of cards sent/new teams etc (which might be what they are thinking).
Also I have no friends and my wife is shit at board games, so it would not be for me.
Totally agree with you though, it for sure looks interesting, if I was younger or at uni I'd probably go for it.
