What happens during a Showdown?

During a Showdown, players have the opportunity to engage in a specific phase of gameplay where they can utilize their SPEED: Action abilities. This is crucial because SPEED: Action abilities allow players to perform powerful actions that can influence the state of the board, making strategic plays against opponents.

In this context, the ability to play SPEED: Action abilities highlights the dynamic aspect of the Showdown phase, where players can react and adapt their strategies based on the current circumstances of the game. It adds depth to the gameplay, allowing for tactical decisions that can significantly alter the outcome of the match.

The other options do not accurately represent the mechanics of a Showdown. While it may be true that certain conditions such as exhausting units or limitations on performing actions can occur in other phases or as a result of specific game mechanics, the essential characteristic of a Showdown is the ability for players to actively engage with SPEED: Action abilities.
