When does a player receive Focus during their opponent's turn?

A player receives Focus when the Showdown begins because this is the specific moment in the game when players have the opportunity to engage in pivotal strategic interactions. Focus is a mechanic that allows players to enhance their gameplay tactics during critical phases of the match, particularly when it concerns facing off against opponents' strategies.

The Showdown signifies the transition into a competitive exchange where both players can utilize their tactics to influence the outcome of the turn. This timing enables players to prepare and respond effectively to their opponent's moves.

Other stages mentioned, such as after resolving abilities, during the scoring step, or at the start of the opponent's turn, do not align with the rules governing the acquisition of Focus. These points do not represent the unique chance to immediately engage with Focus during the decisive Showdown phase, which is essential for effective gameplay strategy.
