Quick open booster pack

Free mode
Win each of the limitation duels.
If you have defeated all of the limited duels and still cannot use three of any cards, go where you can change the cards in your deck. Instead of doing that, go "Option" then press [Down] to choose "Off". Then, instead of "Limited" it will read "Free", meaning free mode. "Limited" indicates limited mode.
All cards
Defeat all the limited tournaments to unlock one copy of every card in the game. Passwords will still work. Doing this also gives you the option of using the "Limited" function in the options menu to unrestrict copies of cards (meaning you can use three copies of cards like Change of Heart and Monster Reborn).
Duplicate cards
This trick requires two Game Boy Advances, a game link cable, and two copies of the game. If you want to have multiple cards of the same type without a lot of work, follow these steps. Go to trade a card for both games. Have the first Game Boy Advance trade the cards that you want to duplicate. Do not trade back. As soon as the cards starts coming back to you, trade a card that you do not need. It will be lost. You will get the card you want on both games. This requires precise timing. You can keep trading cards with the second Game Boy Advance and getting the same card. Do not try and trade the other way around or your cards will be lost.

The easiest opponent to duel is Mokuba Kaiba. He does not play magic cards or trap cards. He also does not play cards face down in defense mode.
Mokuba only plays monsters in defense mode if he attacks Cyber Jar (900/900).
After defeating Mokuba many times, he will get cards such as Magic Jammer, Heavy Storm, Raigeki, and Seven Tools Of A Bandit.
Mokuba is a very easy opponent. Defeat him to obtain easy duel points and booster packs.

Spear Cretin

White Magical Hat
Although this monster has 1,000 attack points, he carries a very rare effect. Every time The White Magical Hat does damage to the opponent, one card will be removed form his or her hand to the Graveyard. A good combo is as follows.
White Magical Hat x3
Robbin' Gobblin x3
Fairy Meteor Crush
Luminous Spark
Magic Thorn
With this combo, the White Magical Hat's ATK will be 1500, and if no cards are on the enemies field, your opponent will lose one to six cards in their hand. Because one Magical Hat attacks and the enemy loses the card in their hand, Robbin' Gobblin will kick in and make them lose the second card. He or she will lose almost every card in their hand, Because one of the White Magical Hats have an equip card to it, no matter what their DEF is (1450 or lower) they will lose LP. Because they lose a card, they will lose an extra 500 LP due to Magic Thorn.

Special Summon Revival Jam without paying 1000 LP
To Special Summon Revival Jam without paying 1000 LP, you must have the following cards in your deck: Revival Jam, Card Of Safe Return, and Solemn Wishes. Summon or set Revival Jam on the field and Activate Card Of Safe Return. This allows you to draw a card when you Special Summon a monster from your graveyard. Set Solemn Wishes face down. On your opponent's turn, let Revival Jam get attacked by your opponent's monster. Pay 1000 LP to Special Summon Revival Jam in your Standby Phase on your turn. Before your turn, activate Solemn Wishes (allows you to gain 500 LP for every card you draw). When you draw, you will gain 500 LP. In Standby Phase, you can Special Summon Revival Jam in face up Defense Position. When you Special Summon a Revival Jam from your Graveyard, you can draw a card (according to Card Of Safe Return effect). After you draw a card, you gain another 500 LP. Your LP will be back to normal.
Pay less LP
If you have Solemn Wishes and Imperial Order both active on the field, you can just pay 200 LP instead of 700 LP.
Opponent actions
Joey: He uses a lot of non-tribute monsters that are pretty strong. These monsters contain Alligator's Sword (1500), Goblin Attack Force (2300), and Gearfried The Iron Knight (1800). Also, one of Joey's favorite trap cards, the Magic Arm Shield, is in his deck. Use cards that deflect Joey's blitzkrieg-like strategy, cards such as the trap cards Mirror Force and Widespread Ruin, or cards that power up your monsters, such as the magic cards Axe or Despair.
Yugi/Yami-Yugi: His strategy is to use his three Magnet Warriors to create Valkirion The Magna Warrior (3500/3850). He also uses three Gemini Elves and Dark Magicians, but the main thing you should look out for are his Magician Of Black Chaos. (2800). Use cards such as Ultimate Offering in order to summon more monsters on the field at a time to destroy Yugi easier. The longer the game, the more it favors Yugi's deck.
Trudsdale: There is not much of a threat when facing Trudsdale. Eventually, he will get strong cards such as Raigeki and Magic Jammer, but for now, he only uses cards such as Fire Reaper (700) and other weak cards. Nearly every strategy will work against him.
Tea: She uses mainly female type monsters, such as Fire Princess (1300) and The Forgiving Maiden(850/2000). The thing that will annoy you is her Maries The Fallen Ones, which increase her lifepoints by 200 points during each of her standby phases. Tea plays more defense than offense; use strong cards and lower the amount of defensive trap and magic cards in your deck.
Seto Kaiba: By far the strongest of the basic duelists. As you might have guessed, Kaiba uses his Blue Eyes (3000). He also has the non-tribute monster Vorce Raider (1900). His most deadly combo is his Cyber Stein (700), which at the cost of 5000 life points, Kaiba can special summon his Blue-Eyes Ultimate Dragon (4500). He will then equip Magamorph to his Blue-Eyes Ultimate, making its attack power 9000. Use lots of healing cards and traps and hope that you get a good hand in the beginning.
Mako: The ocean duelist. His deck revolves around the field card Umi, which allows him to power up his monsters. The monsters for tribute he uses are his Seven Colored Fish and Giant Red Sea Snake, both of which have 1800 attack power. He also uses his Legendary Fisherman (1850) which cannot be attacked while Umi is face up on the field. He also uses the one monster tribute Amphibian Beast (2400). Use field cards to destroy his Umi card and other cards that help power up your own monsters.
Weevil-Man: This opponent is annoying. Weevil uses basic insect tribute monsters, such as Flying Kamakari #2 (1500). However, Weevil is most deadly for his flip effect monsters and normal effect monsters. He uses his three Man Eater Bugs, which automatically destroys one monster; his Needle Worms, which automatically destroy the next five cards in your deck; and his Steel Scorpion, which destroys a non-machine monster attacking it. The solution is the magic card Eradicating Aerosal, which automatically destroys all insect monsters on the field.
Rex: His strategy is simple: attack, attack, attack. He uses his Twin Headed King Rex (1600) a lot. Again, use lots of traps to dispose of his dinos. Also, do not try to focus your deck on over powering his monsters, as Rex's deck revolves on power.
Switching opponents
When these pairs of opponents are in the same territory, if you challenge one you will face the other:
Bakura and Marick
Marick and Odion
Joey and Mai
Kaiba and Mokuba
Morphing opponents
When you challenge one of these opponents, they will sometimes change into another form:
Yami Bakura into Bakura
Yami Yugi into Yugi
Marick into Evil Marick
Challenge Umbra and Lumis. Only Lumis appears. Then, Umbra shows up and tels Lumis to leave. You will face Umbra alone.
Change your targets in target week
After you get your targets, press [Start]. When you get to the Duelist selection screen, press [B] and repeat until you have the desired targets.
Ignored Spellbinding Circle effect
The Spellbinding Circle card states that if the monster us equipped with it is destroyed. Spellbinding Circle is, but if the monster equipped is offered as a tribute, Spellbinding Circle is not destroyed. However if the monster equipped is offered as a tribute, Spellbinding Circle's effect is usually ignored and it is destroyed anyway.
Deleting monsters
If your opponent has two monsters on the field, and you use Change Of Heart on a Magician Of Faith, then use its effect to Change Of Heart another monster. At the end of your turn when your opponent gets his creatures back, one of them will go on top of the other one, deleting the bottom one.
Easy win
To get an extremely easy win in the championships, wait until you see your opponent. If the opponent is not Kaiba Mokuba, turn off the Game Boy Advance, then turn it back on. Repeat this process until your opponent is Kaiba Mokuba. Then, defeat him twice. You will easily win the pack of rare cards from the championships.
First, summon some monsters (three should be fine) on your next turn(s). Try everything to get Blue Eyes White Dragon, then sacrifice one of them to summon Catapult Turtle. Next, play DNA Surgery to change Blue Eyes' monster form to Machine, then use Limiter Removal to double its Attack power to 6,000. Then, play Megamorph to double the Attack power to 12,000. Launch the Dragon with Catapult Turtle. It will wipe out your enemy's LP to 0. Note: This will not always work.
Use the following trick to win in five turns. Play Destiny Board face down on the first one. When it is your opponent's turn, activate Destiny Board. When it is your opponent's turn Spirit Message I will appear before you draw a card.
Many duelists have quite a few high Level/ATK monsters. To prevent them from attacking, activate the Trap Card Gravity Bind ("85742772"), making it so that no level 4 or higher monsters can attack (your monsters included). In addition, the Magic Card The Dark Door ("30606547") makes it that both players can only attack once during a battle phase. To destroy the stronger level 3 or lower monsters quicker, activate the Trap Card Infinite Dismissal ("54109233") so level 3 and lower monsters are automatically destroyed in the end Phase of the turn that they were summoned (including your monsters). Keep Gryphon Wing ("55608151"), Raigeki ("12580477"), Dark Hole ("53129443"), and Monster Reborn ("83764718") in your deck to destroy and retrieve dead monsters, and shoot Harpie's Feather Duster back at your opponent. Eventually, if you have more than forty cards in your deck and hardly and extra drawing cards, your opponent will be drawn out and you will win. This also works for summoning Exodia, except you will need more extra draw cards (Jar Of Greed does well here).
Use the following strategy with an Exodia deck. First, get a Millennium Shield on the field. Then, try to use the Sangan Witch routine. Try every draw tactic you can and you will soon win.
If you lose a duel but do not want it to show in your record, turn the Game Boy Advance off before the screen turns black, after the "You Win/Lose" message appears. If you know you are not going to win early on in the duel, simply turn the Game Boy Advance off at that point. This will not damage your saved game as long as you switch off before the screen turns black, as this is when the auto-save feature starts. The game auto-saves after every duel.
If you have more than one Spear Cretin in your deck (preferably three), you can use its effect to create an unbreakable defense. If one of them is in your graveyard and another is face down on the field and is attacked (and is your only monster), use its effect to bring back your other Spear Cretin in face down defense mode. As long as you have one in your graveyard and one face down on the field, your life points cannot be attacked directly. Watch out for Dark Holes, Raigekis, and other card effects that can destroy Spear Cretin without activating its effect.
Summon a Banisher Of The Light in defense mode equp it with Horn Of Light. Then, play a Grave Robber Retribution and a Blue Eyes White Dragon, but have the Banisher Of The Light in face up defense mode. Every time you attack and destroy a monster, your opponent will lose one hundred life points.
An easy way to win is to play Insect Barrier, then play DNA Surgery and select Insect as the type. From then on, your opponent cannot attack you at all.
When you are dueling, set Nightmare Wheel and Dark Spirit Of The Silent face-down on the field. Make sure your opponent has two monsters on the field. When your opponent is attacking with a monster, activate Dark Spirit Of The Silent (allows another of your opponent's monster to attack instead of the first one.) When asked "Resolve this as part of a chain?", activate Nightmare Wheel (same as spell-binding circle, except your opponent looses 500 life points on each of your standby phases). The monster being targeted by Nightmare Wheel will still attack, even if it is not supposed to.
Easy fusions
Some monsters such as Mystical Sheep #1, Goddess With The Third Eye and Versago The Destroyer can substitute other monsters in a fusion. For example, if you have Summoned Skull in your hand and want to summon B. Skull Dragon by means of Polymerization, you can fuse Summoned Skull with Versago The Destroyer instead of Red Eyes Black Dragon to achieve the same effect. These monsters are very useful as they are universal for all fusion monsters. You can quickly get them from your deck by using the effects of monsters such as Giant Rat, Mystic Tomato and Witch Of The Black Forest.
Easy Limitation Duels
Have three Destiny Boards in your deck and one copy of Spirit Message I , N , A , L. Then the Limitation Duels will be over. Have forty cards in your deck and some cards that can stop the opponent from attacking your LP directly , for example cards such as:
Swords Of Revealing Light: Stop enemy attacking you for three whole turns
Nightmare Steel Cage: Stop two turns of a battle phase of each turn
Raigeki: Destroy enemy monsters
Monster Reborn: Take the strongest card out
Change Of Heart: Brainwash an enemy monster of tribute it
Dark Hole : When at low LP, use it to vanquish powerful monster cards.
Premature Burial: Take out your strongest Graveyard monster or the plan.
Defeating Joey Wheeler
To defeat Joey you must have Crush Card - Trap. When you have three, put them in your dueling deck and activate it when your opponent's monsters are too much for you. However, this will not work when Jinzo is on the field, because he will negate the traps.
Defeating Weevil
Use Light of Intervention ("62867251") so that he cannot activate the flip effects from his Man-Eater Bug and Needle Worm.
Weakening an enemy monster
Have three Snake Fangs on the field face down and have already been played the last turn. Then, activate the three Snake Fangs to reduce a powerful monster that you cannot destroy, Then, activate
