This seems to me like it’s more about bosses than teams and combos. This team would do poorly against the general and the fish and may have a chance against the librarian but it’s only decent match is the baby. Even then bad speed manipulation can ruin that fight. That said, when one takes the fight is just as important as with whom, because upgrading the few skills that one uses to damage the boss can mean the difference between winning and losing (quite literally). Trying to beat a boss out of the gates requires not only the right team but also the right setup and maybe a little help with items. For this team, the sub would have to be the jester because he can not reach the back line. Hope that helps.
