Shuffle Tactics is a deck-building game set in a tactical RPG with roguelike elements. The player’s journey takes place in the Kingdom of Asteria, a land engulfed by the Curse of Flickering. The main goal is to defeat the current ruler, King Oghma, and take the throne. Each attempt is part of a repeating cycle, where defeat by an unknown force returns the player to the beginning of the journey. This structure encourages the discovery of secrets that will help break the endless chain of events.
