is one piece episode 733 filler?

The people on Dressrosa cheer Luffy on as he returns to battle Doflamingo, and Gatz tells him to knock the Shichibukai out in one blow. Doflamingo commends Luffy's entrance but knows that he just got his Haki back and is likely at his limits.

Luffy replies that Doflamingo is also near defeat, and Doflamingo hits Luffy with his string pillars, sending him crashing to the ground. Rebecca turns toward him, only for Doflamingo to attack her next.

However, Law switches Rebecca out with a rock, taking her to his location as Doflamingo destroys the rock.
