Thank you for this very helpful write up! You're not the first one to request something that explains the keywords, so I'll definitely move that up in my to-do list. I agree that it would be good for that to show up on the card somewhere too.
The range isn't on the card, so you weren't dumb. It needs to be there, just trying to figure out how to do it in a way that makes sense.
Those typos are the easiest thing I'll fix all day, so thanks for catching those!
Thanks again for all this helpful feedback, I'll be taking it all into consideration during my next iteration over the game.
