Pro-Dueling - S2-E38
Other mistake: When Crowler and Bonaparte approach Damon and Mathmatica during their duel, Mathmatica appears to have 4000 life points. A couple minutes later, when Mathmatica loses 1000 life points due to Damon correctly guessing which card he would draw, Mathmatica's life points are now 3000 (which then go down to 2000). (00:04:33 - 00:06:53)
Pro-Dueling - S2-E38
Continuity mistake: When Alexis first appears and watches the duel between Jasmine, Mindy and the Maître D, her duel disk on her right arm. A couple seconds later, when she approaches them, the duel disk is on her left arm. (00:11:50 - 00:12:18)
Pro-Dueling - S2-E38
Other mistake: When Damon summons Doron to Mathmatica's side of the field due to Mathmatica activating Illegal Summon, the monster is summoned in defence mode, but the display reads ATK, indicating that it is in attack mode. (00:05:18)
Pro-Dueling - S2-E38
Other mistake: When Alexis activates her Ritual Weapon spell, her Cyber Angel Benten gains 1500 attack points. When this happens, the Life Point display is shown to display the Benten's attack points going from 1800 to 3300, instead of the Attack Point display that should've been shown. (00:13:40)
Pro-Dueling - S2-E38
Other mistake: When the Maître D increases the attack points of his Bacchus monster, the Life Point display is shown to display the attack point count going from 1600 to 1900, and not the Attack Point display that is usually shown. (00:11:09)
