I get a lot of use out of it, and Unliving is my most-played deck. It's nice at the start to go from 3 to 4 (at the net cost of three bricks after production) and I occasionally get to use it to reduce my opponent's Quarry. Even without either taking place, you need seven Unliving in hand to trigger the keyword every two plays, so it's good to have on hand regardless. When its cost was 20, it made a good discard target for Reuse the rubble, though now I'm more likely to use Stone gargoyle if nothing better. All in all, it's a keeper.
