First you need to duel with joey-there are boosters right. First choose red-eyes balck dragon then you'll have 2 magic cards right. Then bakura-choose the mystical elf, then you'll have 1 trap card right, then the next batch weevil-chose the judge man, defeat mai valentine there was a man will give you booster pack there only 1 card and that was obylisk the tormentor
goodluck happy cheating "crossback"
