Does Adlers Needle count as moving a dude via card effects? It is not specifically moving a dude, but rather giving the opponent the option for them to join the posse, so I could see this being argued either way.
Full Moon Brotherhood:
"That dude loses all traits, cannot move via card effects, and cannot refuse callouts."
"Shootout, Boot: Choose an opposing dude at this or an adjacent location not in the shootout. That dude’s controller may have that dude join their posse."
