I've yet to run him in a tournament but I've won several games with him lately. He offers alot of utility for the crew. and unless the opponent has easy access to focus, you can keep him alive a long time (survivalist or a nurse help too). I tend to always run him, guilty and a beater with bigger they are. A few of the Crossroad 7 are wonderful depending on strats & schemes and I like dead outlaws with him more than parker. A&D tends to get outside his control bubble for my taste. Sue, Johan, Emissary are all great fits.
Reading the Desolation trick above.....I need to try that. It may only work once but the chaos will be spectacular.
