I love Owen. I'd keep him in. He opens up a 2HKO with the entire deck. Tobbie is weak against Montana, and we've been seeing a lot of those, so I'd replace him. In a full sentinal deck I like Rick for the high damage, but that increases your vulnerability to SOA, so I'd say Tobbie -> Kyle. Then instead of Skiner, I'd say katja, for an easy finish after a hit from Owen.
