Green Carcassonne Phantom expansion

Carcassonne Phantoms consists of 6 transparent phantoms in 6 colours. The purple phantom is for the gray or pink player. 

Each player gets a phantom of his player color. When placing a follower on a tile, the player may also place his phantom as an additional follower on the same tile. When both the follower and the phantom occupy the same tile, they must be placed on two different features. When the player gets his phantom back from scoring, he may keep it to use in a later turn. The phantom can also be placed by itself, and always counts as a regular follower.
