When I first saw Shudderwock, my immediate thought was pair him up with Servant of Kalimos, Stonehill Defender, and cards like that to refill my hand at some point. So even if they end up nerfing Shudderwock, which by the way, the easiest way would be for Saronite Chain Gang to make a copy of Saronite Chain Gang, not Shudderwork, I'd probably still keep him because I think he's a fun card.
The biggest problem is how long the animations take. I started my OTK turn with him earlier today, went downstairs and had a conversation with my wife about how I needed to go under the house to turn on the water, looked around for the flashlight, came back upstairs to change my pants, and the animations were still going.
