Back 4 Blood uses a card building system, where you can make a card deck around a specific Cleaner. Take Doc, for example. Doc is a healer, so you want her cards to focus on keeping the party alive.
Jim, on the other hand, is your glass cannon DPS. He can dish out a ton of damage, but the other team members have to protect him, or they have lost their primary damage dealer against the Ridden.
Each deck can only hold 15 cards, so you want to mainly focus on weakspot damage as much as possible.
