Play against Necropolis.

A large number of obstacles on the map can play a decisive role against the Orcs. The first turn of the Cyclops can significantly influence the further course of the battle. With a normal ratio in numbers, level, and other factors, the Cyclops' attack eliminates approximately half of the target stack, or even more. However, if the terrain is unfavorable, the Cyclops may not even reach their target, but a landscape densely populated with objects is not always common. And there is no guarantee that the Necromancer will go before the Cyclops, unless they are free units (but I doubt there are any madmen who would choose free units against a Dark Mage, so that they could be controlled or go berserk and destroy 2-3 stacks of their own army). It all depends on luck (possible artifacts, abilities, etc. are not taken into account). Furthermore, Goblin Shamans have an initiative of 9, meaning they will most likely go after the hero and are unlikely to disrupt the first spell (by the way, this does not always work; the chance directly depends on magic, and the Necromancer has plenty of it), which could very well be aimed at the Cyclops if they haven't moved yet.
