Steppin' Out - S2-E4
Continuity mistake: When Johnny summons Water Omotics, it is shown to have 1400 attack points and 1200 defence points, as shown by the point display that appears after the monster is summoned. On Johnny's next turn, in the shot of him placing the Spirit of the Harp monster card on the duel mat, the Water Omotics card can be seen, and it now has 1200 attack points and 1400 defence points.
