If a player on a Two-Headed Giant team is poisoned, what implication does that have for the overall team?

In a Two-Headed Giant format, both players on a team share various game states, including life totals and poison counters. When one player on a team receives a poison counter, it affects not just them but the entire team. Specifically, if one player has been poisoned and receives a total of ten poison counters, the entire team is considered to have lost the game because the poison counters are cumulative for both players. This shared state creates a situation where both players need to be concerned about the number of poison counters present.

The other options present misunderstandings of how poison counters function in this multiplayer format. For example, the notion that only the affected player is at risk ignores the fact that losing due to poison counters applies to both players. The idea that the team must win to help the poisoned player recover misconstrues the mechanics, as simply winning the game doesn't remove poison counters. Lastly, suggesting that the other player remains unaffected fails to recognize the shared nature of game states in a Two-Headed Giant game. Thus, the correct understanding is that both players are at risk when poison counters are involved.
