The only way to unlock Raging Battle is to beat all the dark siners in a duel, and turbo duel. BUt, the only way to do that, is to battle them all all of them in a row, with only 8000 life points for all of them, it does not recharge after each. Then you have to go through the same thing, but turbo dueling them all! Then talk to Crow at the Old HIghway, and you will unlock it.
You can either continually get packs after defeating Duelists, or you can unlock and defeat Trusdale Muto to obtain one of every card.
You must beat any "Structure duelist" with ALL structure decks. The structure decks are unlocked one at a time randomly. I think u just have to keep battling in WC mode to unlock them all.
