Two tourney tested Scum builds I have enjoyed using. I am leaning towards milder non NDru variants for now, however if you can see ranges well and place rocks strategically NDru is still fairly"" viable.
List Kathercisize
Kath HLC crack glitter k4
NDru homer crack glitter
Thug tlt
It removes a B or Y the first round and tends to leave your opponent gob smacked nice and early.
List Bosskinrobbers
Bossk mangler crack K4
NDru homer crack glitter
Kavil tlt crack unhinged
No cheating on those crack shots, primary arc only. Pretty much does the same thing as the Kath build. Bossk does wierd things to 1 agility ships. Like fishing for 5 damage with a direct hit crit. Kavil tempts fate vs Soontir and annoyingly drops 2 damage a turn on most things.
