New Redemption Grab Bag now includes an assortment of 500 cards from five (5) different expansion sets. Available at Cactus website.
You may not look at cards in any draw pile or discard pile (other than the top card of the discard pile) unless a special ability on a card allows a player to search a deck. The deck is always reshuffled when this occurs unless a card states otherwise.
On a semi-related note, do all cards that a player discards either from an ability (Primary Objective) or game rule (reducing hand to 8 at end of turn) have to be made known to the opponent(s) when they are discarded?
Cards removed from a draw pile or player’s hand must be shown to all players before being discarded.
