Well after playing a fair few games with Seamus and McMourning I wanted to branch out a little and I grabbed Leveticus. Now I love the concept and can wrap my head around how he works mainly what I'm thinking about is what to take to get the most out him and all his tricks.
To start with he can take any construct or undead, most of what I see for myself to load him up with is more construct based but I'm really trying to find some more undead.
Secondly Levi is in a really cool and unique position where he and his crew can make use of all suits in the deck. He can use either Crows or Tomes so minions that like Rams and Masks would be a good fit in my mind, although some minions that want either Tomes or Crows can work due to Levi's dual focus.
What I'm currently running: Bete Noir, Killjoy, Belle, Canine Remains, SPA, Alyce, Flesh Construct, Hanged, Jack Daw and Necropunks.
What I'm thinking of adding to the list: Steampunk Arachnids, Watcher, the Riders (when they are all out), Ashes & Dust (obviously when out) and maybe some Stolen
Now I'm not sure about all of those models on the add list and I'm sure I've missed a few that may work well also (maybe Ryle but I'm not 100% convinced). A watcher or two I see as good for objective grabbing and also getting around harmless and pitiful along with deck control so all round good utility models. Stolen I'm not sure about but they are Souless and have a few neat abilities that may help out with Levi generally not having too many significant models on the board (yes I know they're insignificant as well).
Now open for discussion what have other people found works well and do you find you use to get Levi working to his full potential?
