Beat Yugi 5 times in a row in the match duel and and beat him 7 times in the single duel. And then import your whole deck and then beat yugi 1 time in both duel modes. After that export your deck and then beat yugi 4 times in match mode then the screen says "save duel as replay data" press NO then it says "you won 5 limited cards for doing this cheat. Then go to deck construction and take out the following cards:Silver fang,Mammoth graveyard, Mystic clown,Armaill and metal dragon. Now your 5 peices is not in your folder, you must intstantly beat yugi by having your life points 4000 or more than u will find the 5 peices will be in your folder. Take them out and Beat Yugi in single mode one last time to use the 5 peices. Thank
