Can a player in a Two-Headed Giant game exchange life totals with their teammate?

In a Two-Headed Giant game, life totals are tracked collectively for both teammates, and they share the same life total. According to the Comprehensive Rules, there is no mechanism within the game that allows players to exchange life totals with their teammate. Each player contributes to the team's life total, but it remains singular and does not allow for players to swap or alter their individual life totals with one another.

This prohibition stands regardless of player agreement, the turn structure, or card effects because life total management in this format is specifically defined as a shared resource rather than an individual attribute. Therefore, the correct understanding is that life totals cannot be exchanged between teammates.
