okkay bro you have
ASTAROTH TEAM READY
astaroth lead
amon sub
dj sub
herasub
herais sub (when you get her) place another devil atm, like busty hades (you just have to busty your hades)
lead friend --> lucifer//astaroth (i have max leveled evolved astaroth if you want)
LUCIFER TEAM
lucifer lead
vampire sub
hera sub
dj//echidna(depending) sub
yomi sub
lucifer friend
UMIYAMA TEAM.. kushinada team..
valk team...
you just have to decide two teams you want to pursue...
I'd say either valk or luci team for tanky descended...
1) if you are combo-cracking you can go with kushinadahime.. terrific spike lead with an active that lets you chain menace..
menace --> on the attacking turn from mob kushinada passive --> menace//orochi's active
2) or you can go with an umiyama team..
umiyama sample team
umiyama
yomi (change the world will make sure you WILL get the best combo ever
i personally avoid this active as i'm good enough, but it CAN change your world, if you're not averaging 7 combo always)..
valk
adk (busty yours it's always better)
hera//herais --> in your case i think busty vampire is better since i doubt you've skilled hera/herais
and this will rock your world
or there are a lot of other feasible setups for umiyama...
so i'd say that your plateu is --> start using spike team seriously
