How does the game define the effect of the keyword "Unit"?

The correct interpretation of the keyword "Unit" in the context of the game refers to its ability to perform special actions each turn. In many strategy games, a "Unit" typically represents a card or token that has specific capabilities associated with it, such as attacking or using special abilities during gameplay. This distinguishes it from other types of cards that may not have these interactive functions.

Understanding that a Unit can carry out special actions enhances strategic depth, as players can plan their moves around these unique capabilities, leveraging them to achieve victory. These actions could include attacking opponents, defending, or utilizing abilities that impact the game state.

In contrast, other options do not encapsulate the full definition of a Unit. Reference to just creature cards would be too limiting, as Units encompass a broader category. The requirement to stay on the board for a set duration would also misunderstand the flexibility of Units in gameplay. Lastly, stating that Units refer to any card that can be played is inaccurate, as it includes many cards that do not qualify as Units based on their functional capacity within the game.
