Uluk: Ancestral Spirits

From BoardGameGeek:

Ancestral Spirits increases the level of player interaction and tactics by introducing two new types of cards: Mystic Vision and Ancestral Wisdom. You start the game with one Mystic Vision card and get one more whenever you send a tribe to the Temple. They grant you special one-time bonuses and an ability to interfere with your opponents' actions. You also get two Ancestral Wisdom cards at the start, and one more per each visit at the Shaman's Hut. They are secret objectives that get you extra Happiness Points whenever fulfilled during the game, not at the endgame scoring.
