Secondary mechanics expanded?
For Sloane, maybe expansion into keywords including Con and Seedy (and a keyword for "determine control via bullets") - and their "cheatin' and gettin' away with it" theme imported to Lowball. For Lawdogs, I'd like to see more skill support - including Blessed and especially Mad Science - maybe a 1-cost dude to prop up these archetypes. For Morgan, I'd like to see more options for control effects - maybe hitting off the Attire, Horse, and Ranch keywords - including booting or moving other dudes (ex. Dead Billy) or even removal of influence. For 4th Ring, continued expansion into their spell-less archetypes - including Abominations and Mystical Gadgets - continuing with the "hunter" theme (ex. Black Owl). For Eagle Wardens, I'd like to see more support for the mechanics of cards like The Mixer and Remedy - maybe special goods that ace themselves for powerful effects (like +3 stud until sundown or +1 permanent Influence) but may only be attached at Holy Ground locations - and Totems that incentivize interactivity. For 108 Bandits I'd like to see more support for various mechanical themes - maybe Hymns and Abominations - maybe a continuation of the "robin hood" abilities and more mechanical incentives to spread out.
