The Purge

Don't you think that taking 2x Raising Hell instead of 2x Ivor would make more sence? You cound actually use it to bring Bobo back to shoot someone at Point Blank range again. Or does your game plan relies on playing Ivor? (That would be kinda strange, considering that you removed him from the starting posse)

Also, why did you choose Too Much Attention over Unprepared or Recruitment Drive?

And why Soul Blast over Paralyze Mark?

With such sky high pull values, Soul Blast is nuts here. It can easily kill off a lot of small dudes like Philip Swinford, that pesky Allie Hensman, opposing Micah Ryses, Lawrence Blackwood, and Clementine Lepp. I'd almost be tempted to max out Soul Blasts and just play one Blood Curse instead.

Why the "Too much Attention" at all? You only have 4 other 10's, and as mplain said why not unprepared? It's much better in shootouts, which looks like what you're hoping for with the draw structure. You negate an entire dude worth of cards (including spells in mirror matches).
I also like Point Blanks, but you start with 0 dudes who can use that, so it can be a very dead card. Because of that I've removed it from all of my 4R decks. I'd move it to any of the queen actions or the cheating cards. Also I get the point for Morgan's, but the odds you'll pull it, play it, use it, need the 2 skill (With the cards you have) are low.
Finally, with the 3 blood curse you might want to think about 8's. I have won many games with Blood Curse + Rumors.
