Faster duels
Start the game with the -speedy command line parameter.
More cards
Do Match Duel and you will get three cards instead of one. After winning a Match
Duel and you obtain the three cards, you are able to draw three more cards by
clicking the bottom of the screen repeatedly.
Wrong card behavior
While the Trap Card "Magic Thorn" is active on the field, when your opponent
discards any number of cards from the deck (for example, Needle Worm,
Gravekeeper's Servant) it does not count as damage to Life Points, and the card
just says discard. The card was supposed to activate even if your opponent
discards from its deck.
