If an effect sets the life total of each player on a Two-Headed Giant team, what is the procedure?

In a Two-Headed Giant format, players form teams, and each team has a combined life total. When an effect sets the life total of each player on a team, the procedure typically involves the team selecting which player to affect, and the effect only applies to that one player. This approach respects the unique team mechanics of Two-Headed Giant, where decisions and effects often stem from team interactions rather than affecting both team members equally at all times.

The other options suggest simultaneous or equal effects on both players, which misrepresents how life total-setting effects work in this format. The core concept is that the team dynamics allow for targeted effects that can vary between the two team members, making the clarification that only one player is affected by the life total change accurate in this context.
