Yeah, two Terrogheists are pretty essential to any Vampire Counts army to flank the opposition, only problem being their death scream, which, although it is really effective, only has a range of 8 inches. Still, it one of the best-looking and most effective models they've got so it's always worth a try. The Covern Throne/Mortis Engine is also quite effective (which one you use though depends on what army you're versing) not to mention really cool to play as. Crypt Ghouls/Vargheists are pretty cool as well and preform some of the most powerful close combat attacks the
VC's have. Hope this helps and happy playing!
