"you liked the part where zangetsu appears to be Yhwach from a 1000 years ago...? that was the biggest a**pull Kubo has done in the history of bleach..."

That was good storytelling actually. "Zangetsu" was the manifestation of Ichigo's Quincy powers. Yhwach is the progenitor of all Quincies. It makes a whole lot of sense why fake Zangetsu would appear like Yhwach in some form.

The biggest ass pull Kubo did in Bleach was Sasakibe possessing bankai long before all the other alive characters and yet got one-shotted by Ichigo like he was mere fodder.
