  Card Farming (Save File Exploit)

  it works: 0% | it doesn't work: 0%

  To make a copy for a card that you already have, all you need is two memory cards with an identical save file.
  
  

  • Go to the option setting and change the option for autosave to on.
  • Do the same thing for the second memory card.
  • Go to 'arcade mode' and then opt to 'build deck'
  • Remove all cards from your existing custom deck, or simply disassemble the deck.
  • Return to the title screen and remove the first memory card, switch it with the second one, so that the first memory card is in slot 2 and the second memory card is in slot 1.
  • Disassemble all decks for the second memory cards, and then go trading with the first memory card.
  • The second memory card should have twice the number of card after you do the steps above, and transfer all card you want to copy from the second memory card to the first memory card - just press START on the second controller, it means that player 1 transfers the card, not trade it.
  • The first memory card should have the card you desired to copy, repeat the process to make a lot of cards. This trick is useful to copy a story-based signature creature card.
