The Local Legend is a vampire, generally what I do is keep him safe and grind Morois until they can accept the Gift at which point they're relegated to permanent guard duty. That's a short-term strategy though, it's only good for defense. When you do start getting a supply of Childe vampires you get more options. Or not. The Court-limited leaders are kinda stuck in one ideal path.
Basically, use White Court vamps to subvert the raiding barbarians and eventually send a horde of your own to crush all the camps blocking your expansion. Domination isn't limited by the unit cap, so it's an easy way to get a Doomstack of 40 or more when any other player would find themselves restricted to maybe 20 if they're skilled. Then once you've undoubtly lost over half of your orcs, you'll have room to send out another city and start the grind all over again.
Black Court is much the same except raising your slaughtered foes rather than being supernaturally pretty, you just need to risk a "general" vampire to get much use out of grunts like Skeletons. Additionally, the General can also empower other more traditional Undead like Spectres, Drowned, and Diseased Corpses, so there's a bit more wiggle room to make up for needing to protect a key figure during and after the assault.
Red Court is the most difficult and the most fun IMO. The promotion chain encourages you to play fast and loose with their combat odds and doesn't give you a minion-making function to wear a target down for them. I mean, there's still the Necromantic Rite unlocked in the Death Magic tree and such, but you'll still be much more dependent on using Bloodpet/Morroi support tactics than the other two Courts are.
