I think some of Monty's old animation made it into Merc and Yang, plus the fight between Amber, Cinder, Merc and Em. If you look at the credits for those two episodes you can see his name credited for animation work.

I think the only non-Monty fight I've liked this volume was Coco and Yats vs. Merc and Em. That was pretty based.

EDIT:


[hider=by the way]
this episode was fucking based
