Considering some lists with a Verminlord Deceiver General. Was looking for some input on a Command Trait / Artifact loadout. FLGS doesn't make use of Realm Artifacts, so that's out the window.
Gut reactions tend me toward Shadowmaster against heavy shooting/magic armies, else Incredible Agility. Artifact-wise, I'm torn between Shadow Magnet Trinket, Cube of Mists, or Gnawbomb.
The rest of the list is a combination of battleline clanrats, a unit of stormfiends (will expand to 2x3 in time), Warp Lightning cannons, plague monks, a furnace, a bell, arch-warlock, and Skreech. Likely not all of this at once, but those are the tools in the arsenal. Silliness like taking Skitterleap on the bell and throwing both Skreech and the Deceiver forward are definitely on the table.
