  This paper presents a new AI challenge, the Tales of Tribute AI Competition
(TOTAIC), based on a two-player deck-building card game released with the High
Isle chapter of The Elder Scrolls Online. Currently, there is no other AI
competition covering Collectible Card Games (CCG) genre, and there has never
been one that targets a deck-building game. Thus, apart from usual CCG-related
obstacles to overcome, like randomness, hidden information, and large branching
factor, the successful approach additionally requires long-term planning and
versatility. The game can be tackled with multiple approaches, including
classic adversarial search, single-player planning, and Neural Networks-based
algorithms. This paper introduces the competition framework, describes the
rules of the game, and presents the results of a tournament between sample AI
agents.
