The formulation was suggested by Pit for LM; it's exactly what's needed, here it is:
Hit-and-run is prohibited: the attacking hero is not allowed to retreat in the first round of battle if he cast any magic. This prohibition does not apply to the hero who is defending.
Otherwise, according to option 1, it would be possible to find a loophole, for example, by retaliating with a dragonfly against another dragonfly and catching the opponent in the first round, which is unfair.
Also, the magical attack of the Fairy is not considered a trick, because it's the same as using archangels as a trick; for such a maneuver, a decent price should be paid, meaning that in this case, there is no way to inflict significant damage with minimal effort.
I ask that you revert to what was proposed and what people voted for.
