Kastore's team was Kastore himself (neutral), Maximus (evil), Dark Shade (evil), and Tolberti (not in MM3).Notice that Kastore's team judging by their MMIII alignments, contained one good and one neutral character (Kastore himself no less). So it only makes sense to believe one team neede the majority of the cubes for some reason.
Resurrectra's team was Resurrectra herself (good), Sir Caneghem (good), Crag Hack (neutral), and Robert the Wise (not in MM3).
Not that it really matters; by the end of MM3, they all became the same alignment.
