I've got decisions to take for an incoming 2000 pts AoS tournament.
Option 1:
LoN with Nagash, VLoZD, necromancer and 10 black knights. Heavy magic and heavy hitters. Already tested and works nicely.
Option 2:
Try Cities of SIgmar for an even heavier magic phase (yeah, you know the city I'm talking about).
Celestial hurricanum, 2-3 wizards, 30 handgunners, 20 Irondrakes and other things.
Impressive on paper but not tested on the battlefield.
Option 3:
GO WILD WITH THE FUN!
Seraphon with Slann, 3 EotG, Cogs and Dread Saurian.
