Monopoly

When "Monopoly enters the battlefield create X
'Money' where X is the amount of permanents
under every player's control
At the beginning of your upkeep create X
'Money' tokens divided by 2 rounded down
Bid for Control: Opponents may not Purchase
"Monopoly" but must bid a number
Highest bid wins control of "Monopoly" and sacrifices that many non-token permanents
unless "Monopoly's" controller bids higher
