Looking around for advice with Mei as well. Basically ran battleboxes plus Doppelganger/Thunder Archer & Rail Golem, and win on VP or no I've never felt so useless on the table. Part of it was some really bad cards, both out of deck and in hand, but still - little ranged power and smaller threat ranges meant I got Lured in and Miseried to death, or whiffed stuff and got Miseried to death, or had to hit myself and got Miseried to death...you get the picture. I was trying to play to scenario since we had (and both I and my opponent chose) Reckoning, Frame for Murder, and Line in the Sand; I got Frame off and that was it.
In short, ow. Tactical help, if possible, knowing that I presently have the Rail Crew, a couple of Archers, Gamin, and the big guy available as models?
