Two Headed Giant is like 2v2, except there's a shared life total (Each team starts with 30).  
30 life
15 max poison counters
Teammates take their turn during the same time, yet their battlefield is not "shared", thus boosting enchantments that only affect your "battlefield" don't boost your partner's cards.
