Exit Through the Grift Shop
Sorcery
Yell "Who wants a souvenir?" and announce the name of a nonland card in your graveyard. Each player in an Un-game who can hear you may bid life. You start the bidding at 0. The high bidder loses life equal to the high bid. They copy the card and may cast the copy without paying its mana cost. If you didn't win the bid, you gain life equal to the high bid and create that many Treasure tokens.

Players may bid in any order. If two or more players try to place the same bid at the same time, you choose which of them does so. Bidding continues until no one places additional bids and the high bid stands. Players may bid at any time while bidding is in progress. End the bidding in a reasonable time frame and don't drag the bidding on for too long.
