Death Structures

Under the Vampire's influence, the same Bone Dragons and Ghosts work perfectly well ;) There are no fundamental differences from my usual tactics here. But the mass cancel with the immediate elimination of the most dangerous hero... yes, that's interesting! For example, eliminate a priest in the Haven or Sanctuary army - let them figure it out. Or a tactic that might even be more useful in general... Very broad prospects open up. The only thing that worries me is the slight sluggishness on the adventure map - and temporarily storing creatures in the castle is unlikely to be worthwhile. Are there ways to move a group consisting of a devil + hellhound + heroes? (Don't suggest teleportation, we have a fast hero). Maybe the combined speed with a Chaos Sorcerer or a Lich?
