The 2012 Asmodee Special Card set is a set of 3 cards that can be added to any Dixit game simply by shuffling them into the deck before the game. The three cards are:
An aerial scene depicting a knight on a purple dragon, a cowboy on a giant eagle, and a gypsy on a flying carpet. You might recognize this illustration, as it was used as the box cover of Dixit 3!
An image of earth with a halo of fire (or maybe smoke or something else?) surrounding it. There is also a giant hand palm-side up beneath the earth.
A forest scene, where a harp is built into one of the trees and plays a song. Someone has also carved a heart into one of the trees and shot it with an arrow.
These cards are new and not available in the USA (other than being the cover image on the Dixit 3 box!)! The set will be made available in the BoardGameGeek Geek Store beginning in October or November of 2012. These cards are regular part of a european edition of Dixit 3.
