When you put this creature into the battle zone, untap all Dragons in your mana zone.
If "Bolmeteus Samurai Dragon" or a Dragon with "NEX" in its name is in your battle zone, all of your other Dragons get "Power Attacker +4000" and break an additional shield.
"Those who kill just to take the life of the enemy are misguided. One should not take life, but instead destroy evil." -Shadow Sword "Yagyuu" Dragon
