Witch Wars - S6-E21
Continuity mistake: When Paige goes to The Bay Mirror to bring Phoebe potions we see she has 3 different colored potions: green, blue, and orange. She hands the light blue "explosive" to Phoebe, then hands the green one saying it's "acid" but when she hands Phoebe the last potion the camera angle changes and we see that she's again handing her the green one. At this time we see that Phoebe is holding the blue and the orange ones. (00:10:28)

Plot hole: In the beginning of the episode the opening screen row Witch Wars has images of the witch Paige saved before the event actually occurred.
Witch Wars - S6-E21
Visible crew/equipment: While the demons are watching Witch Wars at the bar, when the show's host, Corr, is holding an athame he tells viewers the winner will be awarded a serious power boost, then just as Corr says, "Since the shapeshifter..," in the shot of the demon bar patrons, we see the T-mark (it is not part of the Witch Wars show) taped to the floor under the table. That T-mark is visible again in at least three following shots. (00:23:35)
