At first glance, I didn't think much of this card. It's real expensive for what it does. But, I have begun to include this in my decks. Usually, it won't be worth playing it the turn you find it. That's what initially had me skipping over it. But that's ok. It's ok if you discard it for a resource. Because later on in the game, you might have a turn where a little help and a chump block is exactly what you want to do with your turn because your cards didn't work out for you or you need something to soak while you stay in hero form. And for that, there's Lockjaw.
Better yet, when you are all setup you can just keep using your board and keep playing him every round to keep going.
