Well I play
woc so well I can give you the most help with that.
Your lords will be quite expensive but oh so worth itthey kick @$$ haha.
We have nasty magic tz magic good times also shadow magic and nurgle magic is a nasty combo.
You will not have to spend lots of cash warriors are 16 pts at least so very few models and you can still pack a punch.
If you want a horde marauders rock
mok and
gw is a win.
Can be very competitive especially with chosen star.
Tk are very cool very conpetitive.
Sweet models strong magic tomb guard those guys just don't die.
Kings and princes are super useful.
Vc ghouls are pretty much your core grave guard rock vampire lords are useful.
You will need a lot of zombies and skeles for raising.
The battalion is a good buy for sure.
DE lots of metal don't know too much hydras are great so are the cross bow guys.
Hope this helps without getting into super detail
