Mom deck meant for slow play nightmare in doc+mom team comps where Mom supplements doc and also helps out the team by being the shot caller, marking and sniping mutations.
Doc focuses on bandages and health kits (with medical professional and experienced emt), while mom focuses on healing through pain pills (hence poultice).
Recommended for teams new to nightmare and tend to make mistakes, but at the same time dislike speed running. Hence the increased support capabilities. Once support economy is built up only then damage-oriented cards are added.
