- Also, apparently they have some kind of enmity with the Fabled monsters, that also involves the Mist Valley monsters, due to the card Mind Pollutant, where Fabled Raven is controlling the mind of Mist Valley Thunder Lord, and using it against the Ally of Justice Catastor. That can be a possible answer for the reason which Mist Valley Thunder Lord is holding the crushed remain of Ally of Justice Catastor on it's card artwork. Not to mention that Fabled monsters are all LIGHT.
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".
This deck is easy to get used to even without Light type monsters on the opponent's side of the field. It works pretty well if you know what you're doing.
If using "DNA Transplant", "Lyna the Light Charmer" can help you take over your opponent's monsters (if the Attribute 'LIGHT' is selected with "DNA Transplant"). Also, since all monsters on your field are LIGHT, you can use them to Synchro Summon "Light End Dragon" to your side of the field.
When "DNA Transplant" isn't on the field all your "Ally of Justice" monsters will be DARK and as a result you can Synchro Summon "Dark End Dragon" to your side of the field.
Although "Ally of Justice" are strong when battling LIGHT monsters they can be countered with cards like "Skill Drain", "Destiny HERO - Plasma" and "Angel O7" (even though "Angel O7" is a LIGHT monster he negates any effects on the field). To counter those cards use cards like "Royal Decree" and "Lightning Vortex". "Acid Rain", "Magnetic Mosquito" and "System Down" also hurt the deck because they clear the field of all Machine-Type monsters on the field (especially "System Down" because it banishes them).
