I took one yesterday. It was in a wave serpent with eldrad and 2 warlocks and a farseer with 2 warlocks and howling banshees. They drop out. Activate bladestorm. DJ has enhancement to give him an auto six, I used eldrads doom on a squad of GK terminators. when firing with him pick sustained hits 3. Use fate dice for extra six (can use farseer that is near it) and roll the extra hit. You will avengers 9 hits (with a possibility of 12 if you naturally roll a six for the last dice) then wound roll. You have 9-12 chances to get a 6 for dev wounds. I gave it a fate dice of 6 and rolled 3 natural 6s (I was fighting grey knights and this killed one of the terminators straight away with mortal wounds. I was wounding on 2 because of doom. I rolled 1 1 and re rolled it with our detachment ability and got a 4. He failed 4 saves, killing 2 termies and leaving one on 1 wound . Next we're the warlocks. They used their flame attacks and killed the rest. Banshees were there as a back up.

I know alot of the more experienced players will probably know those already but I thought I'd share for anyone wanting to find something that doesn't involve wraith units
