Plot hole: Jaden activates Miracle Fusion, allowing him to fuse the Elemental Heroes Flame Wingman and Sparkman in his graveyard to summon Shining Flare Wingman. However, Flame Wingman was never sent to Jaden's graveyard. He activated De-Fusion (allowing him to summon Avian and Burstinatrix) when it was about to be destroyed, which meant Flame Wingman was sent back to his deck and not his graveyard. (00:17:13)

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)

Chancellor Shepherd: Jaden, I'll leave it up to you, son.
Jaden Yuki: Ah, these guys couldn't even beat male pattern baldness so there's no way they're going to be able to beat us.
