Ninja Squares (Economy Card Edition)

Ninja Squares is a card placement game where players try to get their own pieces to have certain conditions met, but only get to place the cards of their opponents. Conditions change every time a card is collected for points, so sometimes there will be cascades of points.

Each player is trying to collect five card types in their own color, worth one to five points. Each of those types needs to be bordered by a number of cards corresponding to the point value, except for the elusive fist, which earns you five points only after it is no longer touching any other cards. There are also mystery cards that become more and more valuable as your collection of them grows. But watch out, because there is also a negative card type that gets worse and worse!
