Well, logically, a Mono Squad with dual Dream Starter leads and the right sub units could outclass most squads very easily. A simple example:

Dual Vargas lead   Darvanshel (7*)   Vishra   Kryuk   Randolph

You've got 135% HP buff (Vargas+Vargas+Darv BB)

300% ATK from LS alone    BB per turn, BB fill rate buff, BB when attacked (Vargas+Vargas+Kryuk+Vishra)

Crit chance and Nuker from Randolph    Mitigation and nullification from Darv   Status ailments from Vishra

Massive survivability buffs from Kryuk   Many SP buffs from Vargas, including team Spark damage and Crit damage

That squad easily equals or surpasses most squads, and swapping out some of these units for others wouldn't change much. In fact, there's probably better unit choices that I missed.
