With this build you will never run out of money! First 7 cards are what make this build work. if you have at least 1 friends that can run Weapon Smith keep it not you can remove if you want. If you're friend can run Copper Scavenger, Money Grubbers, and Compound Interest it makes this deck way better but its not needed. This build is good on Karlee for the extra quick slot but its not needed.
