text: In a Two-Headed Giant game, damage and life loss happen to each player individually. If each player on a team is dealt 2 damage, each of those players loses 2 life and the team’s life total goes down by 4. When Archfiend of Despair’s ability resolves, each of those players again loses 2 life and the team’s life total goes down again by 4; they don’t each lose 4 life.
