King Family Auction

Each player reveals cards from the top of their
library until they reveal an artifact. Exile each
artifact revealed this way face up stacked in turn
order with your artifact on top. Each player
shuffles.
Starting with you, each player may bid X for the
artifact on top. When no other player bids on an
artifact, the player with the highest bid pays {x} and puts that artifact onto the battlefield
under their control. Repeat this process for each artifact. X can't be 0.
