Electric team:
Leva V0 (V1 if gunsmoke is important to you)
Lenna V1 (only needs dupe because she is an older doll in the meta.)
Jiangyu V0 (V1 if you want stronger Leva)
Andoris V0 (Andoris is the beginning of dolls that function at V0 thankfully)
Belka V0
Mosin Nagant V4 (a flex pick like belka 90% of the time, V4 lets her work with Leva much better though)

Ice team:
RO V0 (completely usable at V0 or V6, literally no stopping point between)
Alva V0 (V1 if you want to invest a bit to make Ice stronger overall)
Suomi V0
