Tag Team Trial: Part 1 - S1-E10
Other mistake: All monsters in the series with effects are shown to be shaded in a dark orange color and all of the monsters with no effects whatsoever are shown to be shaded in a bright yellow color. Yet Dox's Defense Wall card is shown to be shaded in a bright yellow color (which implies that it is a monster with no effect), despite the fact that Defense Wall has the ability to be the only monster an opponent can attack whilst in defense position.

Return of the Supreme King: Part 3 - S3-E51
Other mistake: When Jaden summons Elemental Hero Clayman in defence mode, the shot pulls out slightly and Jaden says "And now I activate Rainbow Neos' second ability." At this moment, Clayman can be seen on Jaden's duel disk, and the card is placed vertically on the disk, indicating that it is in attack mode. (00:06:55)
Tough Love - S2-E43
Other mistake: When Zane and Aster are talking outside the Duel Academy building, in the shot of Aster saying "I'm just impressed that I beat you on live TV", Zane's deck can be seen inside the duel disk he is wearing. The top card doesn't appear to have the black-coloured oval shape that is usually shown on the cards. (00:02:40)
