Any strategy against black dragon?

[Dabrinko]

I guess I need to clarify. In the deadlands, the black dragons are never alone, but have a contingency of Archers, Vampires and whatnot. (Yes, Target worked for them)

I really don't need them (especially the ranged attackers) to bang more on my staybehind forces who's getting enough pummeling from the dragons as it is.

Right now, summoned thorns or my horsemen (replenishable ftw!) are the major "Target"-target.

After the Black Dragons are vanquished, Target is still effective and let my inquisitors kill the other undeads with ease, and then it's resurrection time.
