Chapter 4: Duel 1

Your opponent is Dueling with a Deck based around "Worm" monsters that have effects that activate upon flipping face-up. Using Spell Cards, they will attack you with monsters with fortified ATK.

Some monsters such as "Worm Yagan" have effects that activate when flipping, but since they are not Flip monsters, they cannot be dealt with using "Ally of Justice Searcher," which is useful when dealing with Flip monsters. Keep on the offensive, but be wary of what your opponent's Set monster could be.

• Reward (Loaner): "Ally of Justice Clausolas" x3
• Reward (My Deck): 150

Loaner Deck

While "Ally of Justice" monsters have powerful effects against LIGHT monsters and face-down Defense Position monsters, there are also monsters that have effects that can be your Achilles' heel.

Try to determine which of your monsters can effectively counter your opponent's in the early stages of the Duel.

Once you get the hang of the Deck, we recommend using cards that support Machine-Types and aim to Synchro Summon your trump card Synchro Monster.

A Deck that utilizes Reptile-Type "Worm" monsters of Level 4 and below. Try using the powerful strategy of sending "Worm Yagan" to the Graveyard with the effect of "Worm Xex", then Special Summoning "Worm Yagan" from the Graveyard in face-down Defense Position with its own effect.

To take advantage of effects that can be activated when a card is flipped, use Spell and Trap cards to supplement ATK and DEF while battling.

Chapter 4.2: Duel 2

Union monsters become Equip Cards that strengthen the monster they are equipped. In addition to effects that increase ATK and DEF, they often have effects that protect from destruction via battle or effect, so when destroying the opponent's monster via battle or a card's effect, make sure to check that the criteria for destruction are met before proceeding. Monsters equipped with "Torque Tune Gear" are particularly threatening as they are treated as Tuners, enabling the opponent to Synchro Summon.

• Reward (Loaner): Protector ("Ally of Justice Catastor")
• Reward (My Deck): 2

Loaner Deck

A Deck that incorporates a myriad of DARK Machine-Type monsters, as well as "Ally of Justice" monsters. Use the effect of the "Ally of Justice" monsters to bring out the effects of other cards. For example, "Ally of Justice Reverse Break" will be destroyed if there is a LIGHT monster on the field, but if you have "Desperado Barrel Dragon" in your hand, you can Special Summon it upon the former's destruction!

A Union Monster is a monster that can be used in two different states: it can become an Equip Card that supports a monster, or conversely, it can be Special Summoned as a monster from its Equip Card state.

Make good use of Union Monster's characteristics to Synchro Summon "Ally of Justice" monsters.

Chapter 4.3: Duel 3

The opponent will attempt to Tribute Summon high-Level "Ally of Justice" monsters while using "Monarch" Spell/Trap Card effects as support. Some cards to be wary of include "The Monarchs Stormforth," which enables your monsters to be Tributed for a Tribute Summon, and "Escalation of the Monarchs," which creates opportunities for Tribute Summoning even when it is not their turn. If 2 Level 8 DARK monsters are played, they may Xyz Summon "Number 22: Zombiestein." Make sure to prevent the Xyz Summon by dealing with the opponent's monsters one at a time.

• Reward (Loaner): Icon ("Ally of Justice Catastor")
• Reward (My Deck): 200

Loaner Deck

The opposing monster will not necessarily be a LIGHT monster. If you cannot take advantage of an "Ally of Justice" monster's effect, use an effect such as that of "DNA Transplant" to change the Attribute of the opposing monsters to LIGHT.

Furthermore, take note of the effect of "Black Garden." Try to use the Special Summoning effect of "Rose Token" to Special Summon "Ally of Justice Cosmic Gateway," or Synchro Summon Synchro Monsters.

Opponent's Deck

This Deck makes use of high-Level "Ally of Justice" monsters by utilizing "Monarch" Spell and Trap Cards.

For example, you can use the effect of "Eidos the Underworld Squire" to Tribute Summon "Ally of Justice Thunder Armor," use the effect of "Mithra the Thunder Vassal" to Special Summon "Ally of Justice Cosmic Gateway," and so on.

Chapter 3: Duel 1

Some "Worm" monsters of Level 5 or higher have effects that do not trigger when they are flipped face-up. If you are too cautious of your opponent's face-down Defense Position monsters, they will end up Tribute Summoning a monster with a high ATK.

It's best to counter by Synchro Summoning monsters with high ATK. In particular, "Hydro Genex" is recommended because it is easy to prepare its Synchro Materials by making full use of "Genex Undine," which has the effect of adding "Genex Controller" to your hand.

• Reward (Loaner): 100
• Reward (My Deck): 150

Loaner Deck

This Deck specializes in Synchro Summoning with "Genex Controller" and monsters of various Attributes.

Synchro Monsters for "Genex" Synchro Monsters sometimes have specified Attributes. If a "Genex" monster on your field doesn't have the Attribute you need, you can change its Attribute with the effect of "Genex Ally Chemistrer." This way, you'll have more chances for Synchro Summoning.

Also, if it is difficult to Synchro Summon, fight on by using cards with high ATK, like "Genex Solar."

Level 5 or higher "Worm" monsters must be Tribute Summoned using monsters as Tributes, but they have high ATK and DEF and powerful effects. To avoid being interrupted before the Tribute Summon, use "Worm Call" and "Card Advance."

"Worm Warlord" is a particularly aggressive monster that can negate the effect of an Effect Monster destroyed in battle, and continue to attack once more. Make this monster the center of your offense as you advance through the Duel.

Chapter 3.2: Duel 2

The "R-Genex" and "Genex Ally" monsters have stronger synergy, making them ready for Synchro Summoning faster.

Watch out for "Genex Ally Triforce." It gains offensive effects depending on the Attribute(s) of the monster(s) used as non-Tuner Synchro Material. Especially when a FIRE monster is used as Synchro Material, you may take effect damage if the monster is destroyed in battle. Fight while paying attention to which "Scrap" monsters have been deployed and when they can activate their effects.

• Reward (Loaner): Protector ("Genex Controller")
• Reward (My Deck): 2

Loaner Deck

This Deck focuses on "Scrap" monsters, which activate effects while destroying their own cards, and combines them with "Genex."

Special Summon waves of monsters by using "Scrap Wyvern" and "Scrap Golem."

If you Synchro Summon "Scrap Dragon" by combining the Special Summoned monster with "Genex Controller", you'll have two different ways to fight: battle with its ATK, or destroy cards with its effect.

Chapter 3.3: Duel 3

A "Fortune Lady" monster's ATK and DEF change with the change in its own Level. Their effects to raise their own Levels and support such as "Time Passage" will make them more powerful monsters.

If your attack is delayed by "Future Visions", which banishes monsters that you or your opponent successfully Normal Summons, "Fortune Lady" monsters' Levels may increase or a powerful monster may be Synchro Summoned. Take advantage of Special Summons, which are unaffected by "Future Visions," to find the path to victory.

Loaner Deck

This Deck utilizes "Armor Ninja" monsters as support for "Genex" Synchro Monsters which require non-Tuner Synchro Materials with specified Attribute.

The "Armor Ninja" monsters have a variety of Attributes, and by using "Air Armor Ninja," which lowers the Level of "Ninja" monsters by 1, and "Flame Armor Ninja," which raises the levels of "Ninja" monsters by 1, you can broaden the range of combinations of Synchro Materials.
