Plot hole: When the collection of rare cards is shown inside Crowler's jacket, the Fusion monster Ojama King can be seen as one of the rare cards. However, Chazz doesn't acquire the Ojama cards until later in the season, and he is unaware of their existence until he gets them. Also, the Ojama cards are depicted as relatively useless, unless used in the right way, so it is extremely doubtful that an Ojama card would be seen in a collection of cards that are depicted as rare and valuable.

Yu-Gi-Oh! GX (2004)
1 plot hole in 5-juu gattai! VWXYZ - chronological order
Starring: Vinnie Penna, Jesse Hooker, Kanako Irie, Tony Salerno
Tag Team Trial: Part 2 - S1-E11
Other mistake: Syrus summons to the field Drillroid and has it attack the Gate Guardian in defense mode, but is blocked by Defence Wall because of its effect, and Defense Wall is destroyed. Because of this, Jaden and Syrus lose 500 Life Points. While it does seem logical that their life points would go down because Drillroid has 1600 attack points and Defense Wall has 2100 defense points, they should not lose life points in the first place. This is mainly due to the fact that Drillroid's effect causes a defense position monster to be destroyed instantly, without losing life points. If Drillroid was capable of destroying Defence Wall, then their life points should have remained at 1700. (00:08:00)

Syrus Truesdale: First, I'm going to summon Gyroid in attack mode.
Para: You must be joking. I am surprised that thing even has an attack mode.
