In a Two-Headed Giant match, what happens if a team has 0 or less life?

In a Two-Headed Giant match, when a team's combined life total reaches 0 or less, they lose the game as a state-based action. State-based actions are automatic checks that the game performs to ensure the rules are being met. Losing life in this context applies to the entire team, and once the life total falls to 0 or below, the game recognizes this condition immediately.

This rule reflects the cooperative aspect of Two-Headed Giant play, where the two players share a life total. If either member's life total contributes to the combined total reaching 0, the team loses the game.

Other considerations, such as penalties or declaring the game a draw, do not apply in this situation because the rules are clear in that a team loses once their life total conditions are not met. As such, the correct outcome is that they lose as a state-based action rather than any continuing penalties or default victories for the opponents.
