Follower Cards are the cards you use to battle the opponent's Followers, as well as directly attack their Character Card should they no longer have any Followers remaining. The amount of damage a Follower takes to its Stamina (STA) when attacked is the attacker's ATK stat minus the DEF stat of the attackee. When attacking a Character directly however, it deals Life damage based on the attacker's Size. If a Follower runs out of Stamina, it is sent to the Grave, and the owner's Character is dealt damage based on the Size of the Follower which died. All Followers require both a slot on the field, and it's Size in Field Size available to be placed on the field.
