Thank you for the suggestion to watch that video at the top of the forum. It definitely did help explain some things (e.g., the differences between Recharge/Reveal etc etc.). i only have the new starting characters for now, although it is good to know that I can use the gold to get more. I wasn't sure what the gold was for.
But, one question that I now have is how do I change out the cards that each character has? In the video, he shows how you can mix and match cards for each character by moving them from the bottom of the card selection screen (sorry, I don't know what it's called ) to the top half of the screen for each character -- e.g., making sure to give one character the crossbow and the other character the mace. However, when I go to that same screen on my iPad I don't have *any* cards showing as "Available" at the bottom half of the screen, even though the different icons show things like 4/4 and 3/3. Why can't I see the cards that I have to choose from?
