Also includes the new Doomtown branding to align it with the broader Deadlands portfolio, plus a formal preview of a new Outlaw dude, Ike Clanton (shown off at Worlds a few weeks ago). It also introduces a new keyword: Rowdy - this is basically shortcut text for things like the Dead Dog Tavern trait, where control is checked via bullets instead of influence.
Ike is going to make a big difference to Sloane starting posses: with Full Moon Brotherhood in the environment Jake Smiley can be a huge risk. I think the card captures a big mouthed bully who needs back up from real muscle pretty well.
