There are four types of cards: Resource cards, Spell cards, Basic Creature cards, and Creature cards with abilities. Upon their initial play, all Creature cards are positioned in the defensive rank. They can remain in this position for as long as necessary, where they are limited to defending or counterattacking. To initiate an attack, a card must be moved to the offensive rank.
Defensive rank (+1 defense, -1 attack): In this rank, you can only defend or counterattack. You gain +1 defense point, and any card placed in this rank costs you -1 offensive point.
Offensive rank (-1 defense, +1 attack): In this rank, you can attack, defend, and counterattack, gaining +1 offensive point. Any card placed in this rank costs you -1 defense point.
