Arena (all 7*):

Rahgan lead    Bestie    Sefia    Zeruiah    Nadore

If you want, switch out Rahgan lead for Hadaron and replace Zeruiah with Rahgan. Don't put Hadaron sub with Rahgan lead, or you'll get his SBB. Since it's single target, you don't want to get it in Arena.

Questing OTKO (all 7*):

Chrome (replace with Elza 7* when released) lead    Hadaron    Reud    Zeruiah    Oguro    Crit buffer friend

Raid (all 7*)

Chrome lead    Reud    Zeruiah    Dion    Hadaron or Colt (depends on situation)    Crit buffer friend
