Made with the new patch in mind. Since money grubbers was nerfed and bots no longer share their copper its a lot harder to get a decent economy early on. So we are playing with cards that gives free health and heals.
1-2 : Support Scavenger and Experienced EMT are a nice combo for the beginning of an act since it will spawn more support items to proc your experienced emt. Also EMT is kinda free health and heals a bunch of trauma.
6 : Poultice, more free heals and pretty good with support scav
7 : Amped Up, you should pick this card if your team as a bunch of trauma at the start of a level. Basically if one of your mates didnt make it in the last level they will respawn with 40 health and 60% trauma. Even if you are full life you will still get the Amped Up effect, even though it doesnt properly appear on your health bar.
11-12 : Medical Pro-Shoulder Bag, at this point you have a decent economy and you can afford buying kits and having more support slot
