use a light sworn deck
You must defeat four clones in a row.
Well you get them in the duelist Genesis pack to get that you must defeat everyone in the jail center 3 times each except that fat dude i forgot his name sorry.
Defeat the following duelists 5 times each: Lutz, Mana, Shirase, Kurihara, Haruka, Giado, Albie, Bass There in New Domino City.
All of the clones have different decks, so one viable strategy is to use a deck strategy that involves the you for recovering life points. This can include Counter Fairies or a Fire Princess deck. Another option is to include defensive cards with your regular deck like "Draining Shield" to recover life points. Remember you can only carry over a maximum of 10,000 might points to the next duel and look for the downloadable card-of-the-day on Nintendo Wi-Fi Connection to obtain certain cards before you even get the booster pack for them.
You actually have to duel people around the area, until they ask you to be their partner. Note: You cannot get a partner in the upper city district, so you have to look for one below the gate where the guard is. Keep in mind that you do have to defeat the people for them to ask.
No way cuz Pokemon are WEAKER than Yugioh.
Yes, it can be obtained in the Stardust Overdrive Booster Pack once you unlock it (to unlock the Booster Pack, talk to MC (New Domino City/Stadium Lobby) and go to the Stadium to defeat all Signer Shadows. [Your Life Points are not reset between each duel])
you need to defeat Bastion 10 times
NO! they would never battle. Lugia is Pokemon and Magician of Black Chaos is yugioh. Also Pokemon have attacks in the hundreds, and yugioh cards have attacks in the thousands.
First you have to beat the great maze by defeating all of the subspace clones and when you so that you have to defeat Tabuu. (Good Luck!)
defeat all level 1 opponents 5 times each
To get a Rai uniform on Yugioh GX Spirit Caller you need to first defeat the opponent. You need to defeat Crowler to get the dual coat and defeat Atticus to get the Hawaiian Shirt. The black and yellow uniform is received after you defeat Chazz and Professor Sartyr.
