In a game of Two-Headed Giant, what is the condition for a team to win if they have more than 0 life?

In a Two-Headed Giant game, the primary condition for a team to win is to reduce the opposing team's life total to 0. Each team in the format consists of two players who share a combined life total, and they collectively face off against another team with their own combined life total. As long as one team has more than 0 life, the primary goal remains the same: to deplete the opponent's life total to zero.

The other potential choices suggest conditions that aren't relevant for determining a win in this format. Eliminating all opponent creatures, while it may significantly weaken the opposing team, does not directly lead to victory. Having a higher total life than the opposing team may offer a strategic advantage, but it does not equate to winning. Additionally, the number of counter cards held does not affect the win condition and is not a viable requirement for victory in Two-Headed Giant. Thus, the correct answer highlights the straightforward win condition of reducing the opponents' life, which is crucial in gameplay strategy.
