Which starting-level magic is the best in Utopia?

Hold on, we know the theory a bit, no double damage!!! ... this isn't Heroes 1 or Heroes 2.
It adds to the normal damage another + the amount of one more base damage of the unit, without any modifiers, so it's far from double. In general, skeletons with 1-3 attack hit for a minimum of all 3 :)

And what if the total damage in the modifiers without considering luck turns out to be less than the base damage? :)

By the way, I'm curious myself.
In one of the tournaments, I remember, Tazar, level seventy-something, took out a Utopia with one swordsman using an elixir.
I wonder: what if the dragons had retaliated with luck?..
