Fairly Basic DMH LD deck.
Shooter values are A / 7 / 8 (14/13/14)
Why not Jacks?
The only relevent Jack for a DMH is Diamonds. The deck includes 4 of those to hit the DMH but is not heavily invested to allow for more utility from 7's (Kidnap, Pinto, Blake Ranch) - You don;t actually need to invest in jacks to make a DMH work.
Try not to start the A value dudes to increase draw power for your shootouts. If they telegraph slide you don't need a strong shooter so you can start Jake, Clem, Lucy, Tommy, Phil for my favourite 7inf anti-slide set up.
Faster on the Draw saves you from SIYE on Wendy / Tommy.
pair of Six Shooters gives you more chances at the DMH if they cheat. You want to get a pair on Tommy and Wendy ASAP.
