Promo Cards are additional traits beyond the base set that introduce new dynamics into Evolution.

Insectivore's eat meat and plant food. Timid is unattackable, but is scared to go to the Watering Hole. Beasts with Trample destroy Food in the Watering Hole to stop opponent's from eating.

In a balanced ecosystem, each new Trait impacts all other Traits as well. You'll need new strategies to survive against creatures using these mighty traits.

You can add any combination of these cards to AI games, or make your own deck for Pass & Play and Private games. You can also add one to public multiplayer games, which is then added into the combined deck everyone plays from.
