Illicit Auctioneer

Infect
When Illicit Auctioneer deals combat damage to
a player, each player reveals cards from the top
of their libraries until they each reveal an artifact
card. Players bid. Each player chooses an artifact
and puts it onto the battlefield under their
control in order of highest to lowest bidder, then
gets poison counters equal to their bid. If any
bids are tied, those players are assigned a revealed artifact at random.
