War of Omens is a strategic card game set in a dark fantasy world, depicting the evolving political and military struggle between three distinct, warring factions. Players will take on the role of a hero representing one of these three factions, with the player's deck representing spells, tricks, techniques, and troops, and take their deck into battle against other players or a computer opponent. War of Omens combines elements from two popular genres of card games: CCGs and Deck-Builders. Players will be able to collect cards and customize their decks, just like in CCGs, but as they sit down to play individual games of War of Omens they'll be buying their cards from the bank each turn, as if they're playing a deck-builder. Opponents in War of Omens will have their own, separate deck; there are no public cards. We call this type of game a Collectible Deck-Builder.
