It all depends on which town I use at first ofcourse, but I mostly prefer chaos and nature that combo really kicks ass once I have reached mid-level of my hero. Cat reflexes, quicksand, mass luck, giant/dragon strenght, lightning bolt, fire ring, summon faerie dragon you name it all serve me well and I have won alot with this combo.
I use a mix of two magic schools for each of my favorite starting towns.
I use one or both of my fav combo depending on which town. But as you can see below, overall, my mix of 2 are chaos and nature, its a great combo I tell ya

Stronghold: Life, Chaos = Pretty useful combo, heal up and bring even more damage to the opposition with DD spells and beef ups like cat reflexes, bloodlust etc. (Since migh have no natural magic, the life and chaos combo are my allround here)
Asylum: Chaos, Nature = Useful too, using the towns natural magic school including mostly DD, enraging spells and adding some help for summoned creatures really helps.
Preserve: Nature, Life = Since the better summon creatures comes late I beef my existing ones with life magic, but I also use luck, quicksand for extra help.
