For Lucy teams i've come with this.
I'm only using Kuzan because i have him fully socketed, he is not needed and about Brook, i'm using him because of his special, which gives me 2 turns, but can be replaced too.
FN Urouge gives 1.5x striker dmg boost, since Lucy's special will be silenced. Colo lucy for orb control/boost and hp reducing. Need lvl 3 anti-despair sockets too, just stall or use specials which reduce despair/dmg and wait for lucy get off despair, after that burst with everything.
