Heiki Strike Alternative 2019

In Heiki Strike Alternative (兵姫ストライク オルタナティブ), the two players each build their own deck from the cards in the box, then deploy their princesses and anthropomorphized weapons to sea and air spaces in a fight to occupy the battlefields. To do this, a player must meet the "occupation conditions" for a battlefield, after which they take the battlefield card. Whoever claims three battlefield cards first wins.

Players will grow stronger over the course of the game through the playing of cards. If a player empties their deck, they shuffle the discarded cards in their reserve to create a new deck, rebuild their base, and now get more resources each turn — but if they run through their deck a third time, they lose.
