Thank You for Not Morphing - S1-E3
Visible crew/equipment: In the scene where Prue comes home and finds Andy inside the manor. There is a shot where if you look behind Andy's shoulder you can see half of the body of the director in the background in the observatory room sitting in a director's chair. (00:16:00)
Duel Identity, Part I - S1-E29
Other mistake: When Yugi summons Summoned Skull, the defence points are displayed as 2300. Summoned Skull has 1200 defence points every other time it is shown. (00:09:07)
League Finals! Full Battle 6 vs 6!! - S5-E60
Continuity mistake: When Ash and Brock are at a table, the front Ash's hat is red, and the back is white, but in the next shot, the front of it is white, and the back is red. (00:09:28)
Buttercrush / Fuzzy Logic - S1-E4
Continuity mistake: When Buttercup punches a hole in the wall to see her sisters are being lowered into lava, the hole's initially quite small. In the next shot, the hole is noticeably bigger.
