My intention was just one deck. Test should be rare, only a few per game session. I’d say 3-5 players is a good size.
When you attack on your turn, you draw up to your attribute, and that’s it. You can’t play as many as you want , but other players can combo off your card and play matching suits/ranks from their hand, like in crazy eights.
Good questions! There is no correct way to play, but I will be tweaking this as I go to make it clearer. Thank you!
