Episode Title:
Sinister Secrets, Part 3.
Episode Description:
Yugi decides to help Leon get rid of the Golden Castle of Stromberg, but this proves to be challenging as not only is it unaffected by card effects, it forces all monsters to battle and discards half of Yugi's Deck each turn. This proves to be its undoing, however, as he's left with one card and so can't discard half of it, destroying the card. Leon fights valiantly but loses to Yugi's Dark Magician. Zigfried is furious with this, but Leon manages to calm him down and forgives him. Yugi and his best friends are finally able to go back home.
