I might consider a Grey Seer, Warp Lightning Vortex, and the either another Endless or potential Triumph with the last 20pts. It would allow you to stay pure for the Stormfiends as Battleline, and being able to send a unit of Stormfiends through a Gnawhole after Skitterleaping the Bombadier to that same Gnawhole opens up the MMMWP + Warpstone Spark shenanigans.
