Combat Knife is for small 1 or 2 ridden that sneak though your front line so you can knife without having to swap weapons or awkardly try to hit with sniper.
Movment speed / stam cards are place where they are for act 1. You can pick in different order for different acts.
Safe room recovery can be gotten earlier based on your play style but should be 10th card at latest.
Last 5 cards are more optinal flex picks based on what you like. I dont like glass cannon since it makes you so easy to kill but it is a really good card if you play with less mistakes.
