Yeah I've struggled with having a kinda small playtest sample on this game BUT I think the behind the scenes is that it is swingy and I chose to make it 'win more often than lose' if it is gonna swing. I do think I will be adjusting some stuff and giving players less cards in their hands.
2-7 might be a good idea given the 'card economy' and how you can get a lot of help.
Thanks so much for feedback!
