I just finished a 50ss game against Lady Justice. I took Tara's crew, plus three Death Marshals. Strategy was Squatter's Rights.
I didn't try anything too tricky in the start, but sent Tara off to outflank some models while the void wretches ran for the corners to tag squatter markers. The rest of the crew went right into the middle.
It was a fun game, and I thought that I was on the losing end for the first half of the game. Then the Nothing Beast escaped the coffin an enemy Death Marshal had tossed him into and just went to town, Obliterating models left and right.
At one point, Tara used Eternal Journey to teleport back to her deployment zone at the top of the turn, right after Lady J had run up to hack at Karina and a Death Marshal. Lady J ended up stuck in one of my Dead Marshal's coffins for most of the game, while Karine layered on the burning on slow and Tara hit people with her greatsword.
Tara's quite fun with lots of little tricks, and being able to reactivate at the end of the turn is quite awesome. They're pretty fragile, but the Death Marshals bring some much-needed resistance to the list. I'm looking forward to playing around with some other Resser models as well; Flesh Constructs could be quite fun, I think.
All in all, a very thumbs up for the Herald of Obliteration crew.
