My group has been having this problem as well. We have tried two different options, one is to put the cards in the treasure deck as tiers as @Pending Forum Suspension mentions. The other was to increase the number of cards you turn over when you open a chest/ buy equipment. We are tending to use the latter option more as it can get equipment on more of the party.
Hello, I have recently started playing Guild Ball again and thought I would finally use my forum account. We have got a small community learning the game in the Notts-Yorkshire border area. If anyone is in the Dinnington area and wants to drop by to say hello or for a game that would be great. Anyone who is in the area and wants a demo game is more than welcome. Mike
