New Redemption Grab Bag now includes an assortment of 500 cards from five (5) different expansion sets. Available at Cactus website.
I had actually considered the possibility of allowing single-color-text-free sites to be added at will, same as generic lost souls (Of course adhering to the usual deck construction rules). Keep in mind, sites are much less powerful in a format where decks are highly likely to be comprised of many different brigade colors. Can you elaborate on your feelings with regard to sites?
The main problem with sites in a multi-player game is NOT that no one can get into them. Instead what usually happens is that there is one player who CAN get into them, and the player using the sites doesn't realize this and keeps putting souls in their site. Thus one player gains a huge advantage simply because someone else doesn't know how to distribute souls in multi-player. This can be very frustrating.
