Baird, Guardião do Argivo
Criatura Lendária — Humano Soldado
2 / 4
Vigilância
As criaturas não podem atacar você nem um planeswalker que você controla, a menos que seu controlador pague

para cada uma daquelas criaturas.
In a Two-Headed Giant game, creatures can attack your teammate and planeswalkers your teammate controls without requiring a mana payment. This is a change from previous rules.
If you control Baird, your opponents can choose not to pay to attack with a creature that attacks "if able." If there's no other player, planeswalker, or battle to attack, that creature simply doesn't attack.
