ton adversaire pourra choisir de ne pas t'attaquer ou de payer pour chaque créature avec lesquelles il veut t'attaquer.

If, during the enchanted player's declare attackers step, a creature he or she controls is tapped, is affected by a spell or ability that says it can't attack, or hasn't been under that player's control continuously since the turn began (and doesn't have haste), then it doesn't attack. If there's a cost associated with having the creature attack, the player isn't forced to pay that cost, so it doesn't have to attack in that case either.
