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)

1 plot hole in The Art of the Duel - chronological order
Starring: Vinnie Penna, Jesse Hooker, Kanako Irie, Tony Salerno
Continuity mistake: At the end of the battle between Jaden Yuki and Gravekeeper's Chief, just as the explosion settles, in one shot you see the Gravekeeper's Spear card to the left of Gravekeeper's Chief on the duel disk. However in the next shot Gravekeeper's Spear is replaced with Magician of Black Chaos, which Chief neither has in his deck or ever played in the match. (00:13:35)

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.
