On this distant star, each tribe or clan fights to ultimately reign supreme. For the longest time, the war just waged on, with no one group holding the advantage. However, this battle that no one thought would ever end was suddenly brought to an abrupt halt, as the "Worms", invaders from outer space, suddenly crashed on the planet.
To combat the invaders, the tribes and clans were forced to form a truce and unite together. The four tribes that were the most powerful forces on the continent form their own organization, "Ally of Justice". Bringing together each of their technologies and crafts, they began to develop anti-Worm weapons.
This archetype is rather unique among all others. Most archetypes tend to not focus exclusively upon destroying one particular category of opposing monsters. Indeed, against most Decks many of the cards in this Archetype will be useless. Fortunately, "DNA Transplant" can be used to set all opposing monsters to LIGHT to benefit from their effects while protecting it with "Imperial Custom".
