Plot hole: When Marcel is standing in an abandoned area, he hears Bonaparte shout his name. Adrian is then seen standing a short distance behind Marcel, and then hides once he sees Bonaparte approaching. There's no way Bonaparte didn't see Adrian. Even if Adrian hid, Bonaparte was already close enough to see Marcel, so he should have seen Adrian as well, or at the very least, seen him on his way to find Marcel. (00:17:10)
Other mistake: After Jesse summons Sapphire Pegasus, he says he can now summon another Crystal Beast in his spell and trap card zone. In a close-up of his hand, there are four cards, and we can see Ruby Carbuncle is on the right-hand side. Jesse then reaches for the trap card next to Ruby Carbuncle, but then Jesse summons Ruby Carbuncle in his spell and trap zone despite not picking it. (00:15:10)
