Rulings
In a Two-Headed Giant game, creatures can attack your teammate and planeswalkers your teammate controls without requiring a mana payment.

Your opponents can choose not to pay to attack with a creature that attacks “if able.” If there's no other player or planeswalker to attack, that creature simply doesn't attack.
