Become a demon summoner in this roguelike deckbuilder. Discover forgotten sorceries, cursed enchantments and powerful creatures as you craft the perfect deck to crush your enemies and serve your dark queen.
Run-based deckbuilding
Build a new deck each run as you progress through the story, unlocking harder enemies and more cards to build around.
Creatures, sorceries, and enchantments
Creatures fight for one turn, sorceries resolve immediately, and enchantments last for the whole combat.
150+ cards
Rare cards define key archetypes, while the rest of the card pool gives you flexible ways to support and adapt each build.
