Other mistake: When Rebecca summons Cannon Soldier to the field, the attack and defence points display shows that it has 400 attack points. Cannon Soldier has 1400 attack points, as shown when it can be seen on Rebecca's duel mat. (00:16:38)

Character mistake: Yugi mistakenly says if he doesn't get a monster out to defend himself Mai can attack him directly, which wouldn't be possible since the rules of Duel Monsters during the Duelist Kingdom arc forbade direct attacks on defenseless opponents. That rule wouldn't be implemented until the Battle City arc.
