Market is an innovation of Redemption CCG - The Third Era, and it is the place where you can sell Cards or buy those offered for sale by other Players.
Twelve Cards are visible on the Market and are updated every hour, the timer on the page indicates the time remaining for next refresh.
From Market you can also access to Personal Market (and vice versa), which is the set of Cards put up for sale by the Player. Cards will remain on sale for 5 days, after which, if unsold, they will return to Collection.
