Share cards in co-op so you can play co-op with new Faeria players

I want to play Oversky co-op with my friend, but he has never played Faeria before, and doesn’t have any of his own cards. I’ll never get him to play with me if he has to put in 40 hour to get a decent card pool.

That’s why I want a “co-op guest” mode where my friend can play co-op with me and use any of the cards on my account.
