If you have Cyclops, you could also consider:
Joan with Sniper Shot (40% ATK Debuff (20% A + 20% B); 20% B Def Debuff)
Baal U - 30% Elem. Resist Debuff
Cyclops - 15% C ATK Debuff -- So 50% ATK/DEF (Elem) Debuff
Thor
Brahma Awakened
With Joan and cyclops, you still have the burst gauge up (without the hp loss), damage cut and ATK debuff that Raiko has, plus an aflliction cleanse.
Thor and/or Brahma can be changed if a situation calls for other himes that are better suited for it.
