I like the way you've adapted Zombie World-like card draw mechanics. The drawn card text eliminates a cognitive step. In my game, they have to look at the highest die and then perform a literal table lookup to know how to interpret it. Now granted, the remit was for experienced GMs and any GM worth their salt will do FitD 6/4-5/3- interpretation without a moment's thought but the new players involved might not find it so easy, and even if they do, the elimination of snags / friction here is paramount. Great thought!
