Continuity mistake: After Para has drawn Sanga of the Thunder, the shot cuts to a reverse angle panning around Jaden and Syrus where Jaden says "You've got to be kidding me. Another level 7 monster?" Near the end of this shot, Para places the Sanga of the Thunder card into the cards already in his hand. Next shot, he places the same card into the exact same cards in his hand a second time.

Tag Team Trial: Part 2 - S1-E11
Continuity mistake: After Jaden has summoned on out the Elemental Hero Tempest card to the field, Bastion says it still can't beat the Dark Guardian. The shot then pans over to Alexis where she then replies "Bastion, just whose side are you on?" As she says this, behind her is another row of seats. The previous row of seats behind her are almost directly behind the seats Bastion and Alexis are sitting on. From an instant big close-up of Alexis thinking to herself "I hope you know what you're doing, Jaden", the row of seats behind her are now no longer pointing directly behind their seats. The half way point are now in fact pointing directly at the edge of one of the seats she and Bastion are sitting at. (00:13:15)

The buildings coming from the Skyscraper card are shown to be ascending upwards and Jaden at this current moment is shown to be looking straight upwards at the Skyscraper card. As Jaden says "Ever hear you should never play in a construction zone" in the shot following, he is suddenly looking straight forwards at the Paradox brothers. (00:13:40)
Continuity mistake: When Bastion opens the door to his dorm room to let Jaden and Syrus in, the bag he is holding has a baseball bat sticking out of one side of the bag.

(00:05:40)
Continuity mistake: When Jaden and Syrus are sitting at the Ra Yellow cafeteria with Bastion, in the shot where Jaden says "Well you deserve it", both he and Syrus have knives and forks in their hands. But in the next shot, the utensils in their hands have disappeared. (00:07:10)

Continuity mistake: After Jaden summons Sparkman to the field and says "Monkey see, monkey do", the shot cuts to Wheeler, before panning over to Jasmine lying on the tree.
