Trying to figure out a B skill for Olivia, I was thinking that R Tomebreaker would be good so she wouldn't get doubled against Red Tome Users, but thinking Vantage or Seal Attack/Defense might work decently, or Wings Of Mercy perhaps?
Teleportation is always fun. I decided to revamp Azura from the start since I pulled her crap IVs. A spur C skill is ideal (not enough SP yet), I gave her Escape Route and Fury to increase her bulk, since I didn't luck out and got a - atk/ +def Azura. Gonna give her a defensive special when I get a unit with sacred cowl. With the tempest going on, she can't stay high health forever, so escape route is useful. Save wings of mercy for a healer with rehabilitate.
I've got Wings of Mercy 3 on mine. I use her mainly for dance support and as a green killer. Right now I use her on a team where other units (Linde, Setsuna) have Escape Route 3 so it gets pretty fun sometimes being able to drop below 50% on my escape units and mercy fly basically wherever I want and target green units easily at the end of the battle.
