Shamans

About Shamans, from BoardGameGeek:

Shamans try to restore harmony in a world threatened by Shadows. You'll need to pick a side. The game combines with ingenuity: hidden roles, competitive play and an original card playing mechanic. Each played card allows you to stabilise the spirit world, perform a Ritual, acquire an Artefact ; and together they will bring you closer to the final showdown between Shadows and Shamans. When time comes, the victor will be the one who managed to read through his rivals and stuck to the right side in this never-ending confrontation. -description from the publisher (translated)
