I'm about to pull Flins and I need to know past Columbina and Ineffa, who I put in the 4th slot. I heard Durin c2 was enough to overpower Sucrose as a 4th, but these are my options:

C1 Nicole
C6R2 Durin
C6R3 Xilonen
C6R1 Citlali (for massive c2 EM buffs - Idk if cryo will mess up the lunar charge or not I'm very new to lunar.
Orrrrr the reliable ol sucrose?

I've heard Xilonen is usually going to be the best, but I wanted to see opinions on that 4th slot from all the dedicated mains out there
