Covetous Auction

Each player may bid an amount of cards from their graveyard for control of target creature.
You start the bidding with a bid of 0. In turn order, each player may top the high bid. The bidding ends if the high bid stands. The high bidder exiles cards from their graveyard equal to the high bid and gains control of the creature. (This effect lasts indefinitely.)
