Tag Team Trial: Part 1 - S1-E10
Other mistake: When Jaden explains Elemental Hero Rampart Blaster's ability to Syrus and the Paradox Brothers, Jaden has Rampart Blaster attack the brothers directly. Just as Jaden says "Blast them with rampart mirage!", Elemental Hero Rampart Blaster is in defense mode somehow standing on top of the Elemental Hero Clayman card, rather than the Elemental Hero Rampart Blaster card.
