I don't remember exactly, but I think there was some issue with the animation of that horse on the battle map...

Is the knight's horse too overdressed? And if you cut off a unicorn's horn, will there be a hole? And what if you replace the entire head and cover the scar with something (like a scarf)?
The main issue is probably the horse running while flying, but that's tolerable. I remember allowing the Nightmares of Inferno to fly. That was cool! ))

Or maybe someone could create a model of a Black Knight with a scythe of the undead instead of a sword (or does such a unit already exist in Heroes of Might and Magic?). I want to create a proper alternate upgrade for the Death Knight. Often, it's just a retexture, and it's not very pretty (either pink or purple).
