The Rival can always buy a Building Card. On the Rival's turn, it selects the highest victory point Building Card available from the Mats where it has Posse Tokens. In case of a tie between point values, the Rival selects by going clockwise from the Town Hall. If the Rival has the "Leftover" spot, it does not buy a second Building Card. If the Rival must advance an industry, note the leftmost symbol on the Building Card it bought first that round. Advance that industry. If that Industry Token cannot advance, use the next symbol list on the Building Card, moving to the next Building Card owned, if needed.
