BioShock Infinite card set for any card set I don't have a level 5 badge on owned or not owned games, worth equally or more than the value of the BioShock Infinite card set. Any other cards in my inventory are also up for trade, excluding sale event cards, and cards from games I don't have a level 5 badge on. All duplicate chat emoticons and backgrounds are also up for trade either for another chat emoticon or background, or gems.
