During the summer solstice, Sioux tribes used to send the young, aspiring sorcerers to the Great Shaman. Each of them had to show his communion with Waka Tanka, the great spirit of every living thing, with having one of the tribe`s totemic animals appearing before the great fire. Woe to the one whos incantations failed. Some tribesmen don`t hesitate to use devious strategies to hide their weakness, but other would-be shamans keep watch. Win the favor of the titular Waka Tanka in this card game of bluffing and deception.
