Who controls and makes decisions for battlefield abilities while it remains uncontrolled?

The correct response is that the active player, often referred to as the Turn Player, controls and makes decisions regarding battlefield abilities while they remain uncontrolled. This means that during their turn, the active player has the authority to utilize these abilities as part of their strategy.

Typically, uncontrolled battlefield abilities are those that have not yet been claimed or activated by a specific player. The Turn Player is empowered to manage these abilities effectively, allowing them to leverage potential advantages in the game. This control is crucial during gameplay, as it enables the active player to dictate the flow of the match and influence the battlefield dynamics, taking advantage of any opportunities presented by the uncontrolled abilities.

The passive player, or any non-active player, does not have the ability to interact with battlefield abilities that are currently uncontrolled. The non-active player is still engaged in the game but is limited to responding to the active player's decisions. Similarly, the player with the highest score does not have any special privileges regarding the management of uncontrolled abilities. Instead, the focus lies solely with the Turn Player, reinforcing their role in tactical decision-making and gameplay progression.
