I just noticed that the custom heros are listed in the Reg definitions with the normal cards. For example, the list of prophets is not just Elijah, Moses, Daniel, etc but includes the players custom heros. IMO this is not necessary and more confusing than helpful. If I'm trying to look through an already long list to find prophets to include in my deck, it is harder because of all the extra names. Especially considering that many of the names in the Chrisian community are Biblical so its not immediately obvious if the name in the list is a card that I can play with or some other player. If you want to look up a players card to see if it is a prophet then it is easy enough to do that in the custom hero list.
I just looked at musicians and I'm pretty sure there are more players in that list than normal Redemption cards. It gives a very wrong impression of how many musicians are available in the game.
