I think it is something like building temple, fort and a lab to every province, and when enemy comes to siege it, you harass him with spells that send one-use armies and maybe supercombatants. Vampire Queen, before she was made more expensive, was very useful on this as she was flying, ethereal and had life drain as ana innate ability, as well as being able to have enough magics to cover most buffs and Cloud Trapeze. Norfleet didn't use her immortality as she was died almost never when properly decked with items, but it still healed her afflictions and I think helped in early province grabbing.

I have never played with or versus this strategy, so I might have understood some facts wrong. I only read about it in this forum. Do a search for 'castling'.
