This game simulates the battle of Lutzen during the 30 years war.
The main part of the game consists of four decks: German, Imperial, Swede, and Fate. The first three are unit decks and the last is an administrative deck. The Imperial and Swede Decks (and to a lesser extent the German Deck) are composed of various kinds of cards (Unit cards, Tactics cards, Terrain cards, Tactical Leader cards, and Commander cards).
