How to deepstrike a Praetor?

Hi, I am trying to create an Atramentar heavy​ Night Lords Zone Mortalis list with Sevatar as the Praetor, due to misreading the deepstrike rule I was under the impression that consul could join units and deepstrike along side them, but I discovered that all units must have deepstrike to be able to do so. If I have Sevatar (and/or any consul, really) join a squad of Atramentar/Contekar is there anyway to be able to deepstike that unit, aside from bringing​ a Warmonger?

Thanks
