When your battling, sometimes you think you can use law cards as defense. Well you can. You can use law cards called "Dmg2: Human". There is also Dmg2:Bangaa, Dmg2: Nu Mou, Dmg2: Viera, and Dmg2: Moogle. When your battling, and you have a human on your side, and the opposite clan does not, you can use the Dmg2: Human law card. So when your opponent gives damage to your human, they will get a yellow card. If they do not have a medal beside their name, and they kill the human, they will get a red card. You can use this trick with a bangaa, viera, nu mou, or moogle also.
