how about restricting it to only be able to cast once every so many turns? If that's possible, I think that would limit the overpoweredness (yeah I made that word up) of the spell.
Say limit to only being able to cast it once every 3 turns, or once every 5 turns. This would keep archmages from stealing a unit once per turn.
And while the logic and math is quite.... odd from the OP, I can agree that it can be 3. Archmage steals uber-unit from enemy, then archmage uses that unit to kill and enemy unit in the same turn. That's +1 for gaining a free unit, +1 for taking a unit from the enemy, and +1 for killing another one of the enemies units.
Summons however give you a unit for the turn, and he might kill a unit in his wake. Often times I have found they are only good at weakening strong city defenders late in the game for your stack to go up against. Once those highly promoted archers are an effective strength of 20+, a summon isn't going to do much here. However, you dominate that unit, you get a decent archer unit for free and right up with your stack, usually ready to move or attack. And the enemy loses its best chance at stopping some of your units from taking his city.
So, is there any way to limit a spells frequency so it can only be cast once per so many turns?
