Outlaws and Cheatin'
it makes sense that Outlaws would have cheatin' as a faction identity, but it has always been a tricky beast to design around. Usually a cheatin' shootout hand will be the inherently better hand, and thus already be paying dividends as long as it doesn't get punished.
Abigail offers a risky solution, cheat in order to discard an opposing goods or spell. In an ideal situation, you will be the lowball winner and discard a Quickdraw Handgun or Lemat Pistol at the risk of whatever cheatin' punishment might be hiding in their play hand.
or it is Abigail on a suicide mission to discard a Yagn's Mechanical Skeleton.
she is a thieving minx - on top of all of that risk she wants to be paid twice the going rate for a shootist.
