How should an effect stating a player cannot get poison counters be handled in a Two-Headed Giant game?

In a Two-Headed Giant game, players team up with a shared life total, and interactions often affect the team rather than just individual players. When an effect specifies that a player cannot get poison counters, it is important to interpret that effect in the context of teamwork.

The correct understanding is that since players are on a team, if one player cannot gain poison counters, it extends to their entire team. This means that no member of their team can receive poison counters as a result of that effect. This is due to the collaborative nature of Two-Headed Giant, where effects that impact one member of a team will impact the team as a whole if they are related to that player's ability.

Other choices suggest scenarios that either isolate the effect to a single player or misinterpret how team dynamics work in this format. For instance, asserting that a player's team can still gain poison counters from other sources overlooks the fact that the restriction applies universally to the team. Therefore, the comprehensive understanding of the effect, when applied to a Two-Headed Giant setting, confirms that the team's overall status regarding poison counters is directly influenced by the specific stipulation made for the player.
