To reveal a card is to show it publicly for all other players to see. This can be done from your hand, your deck, or your discard pile; any area whose contents are not public knowledge. Once revealed, there is usually an instruction given for what to do with the card; if there is none, it is assumed that you put it back where it came from. Many cards reveal for different reasons; Digging cards reveal cards until revealing one meeting their condition, and Reactions are usually revealed when they are activated. One card. Patron, has a special effect that is triggered when it is revealed by some other card.
However, if a card says to look at another card, you explicitly do not show it to other players, but you similarly put it back where it came from if no other instruction is given.
 Official Rules
- When a player reveals a card, he or she shows a card to all players and then returns it to wherever it came from (unless instructed specifically to put it elsewhere).
- If the player is required to reveal cards from the top of his Deck, and he does not have enough cards, he shuffles in order to reveal the required number of cards.
