7 Wonders: Cities
7 Wonders: Cities, the second expansion for 7 Wonders, includes optional team rules, a new type of card (black, representing the remains of cities), and new cards of old types (two new wonders: Petras and Byzantium, new guild and leader cards associated with black cards). This expansion is more aggressive, with greatly increased interaction between players, who are still trying to score more points than anyone else.

The new black cards have a variety of effects, with nine cards being available in each age. Effects include:
