My collection so far that i use for warhammer 40k but i have found a way to use for fantasy
Great unclean one (Games workshop)
Great unclean one (Forge world)
2 Heralds
1 Herald on a Palanquin
2 Plagueridden
2 Standard Bearers
2 Musicians
24 Plaguebearers
1 Plaguebringer on a Plague Drone
1 Musician on a Plague Drone
1 Standard Bearer on aPlague Drones
4 Plague Drones
2 Beast of Nurgle
6 Nurglings
2 Daemon Prince with wings of nurgle
So my question is what should i get more of and what should formations do work and dont work in a game of warhammer fantasy for this sort of army.
