Board Game Arena

Hi all been playing space base for approx 2 months now love the game , I'm aware of the many combos you can utilise during the game but what I think would be a good addition is a option to trade a card with another player in game , what y'all think?

Sounds cool!
But sadly, no house rules on bga.
And plz use game forum: https://boardgamearena.com/forum/viewforum.php?f=535
