Tide Duel, a card game from a 1962 that never happened

Field notes

The proposed game uses a fifteen-card deck limited to forty-five points, with the player’s entire deck available from the first turn rather than drawn gradually. Each turn combines simultaneous sealed orders with three-lane combat, while faction matchups give the setting a rock-paper-scissors structure: Ember beats Stone, Stone beats Tide, and Tide beats Ember. The page also describes a balancing system in which card costs are recalculated from observed win rates, although that system is presented as part of the planned game.
