Skill Upgrades?
Probably wouldn't be the greatest idea, but how would a skill upgrade system like the one in the old Modern Warfare games sound? Like, after a while of using it or completing challenges, you would get an upgraded version of the skill cards, similar to how it was in Modern Warfare (Slight of Hand would become Slight of Hand Pro). Like the basic Quake would only affect regular zombies, but the upgraded version can stun the Apex variants. It would be exclusive to NG+ obviously, but it would give players more reason to play it outside of just completing the story again on a slightly harder difficulty.
