Héroes with healing skills

Anyone with Reciprocal Aid, Ardent Sacrifice, Micaiah because of Sacrifice, and a healer.

Obviously
Wrys
Azama
Mist
and best grill Lucius.

I would like green Olwen (renewal), Elincia (ardent sacrifice) and Faye (noontime) but is hard to guess this one, they might as well just use healers.

Initially I didn't think a cleric would show up, but now that Veronica has showed up with a kit like that, I think it's a bit more likely.

Anybody who comes with renewal or healing specials is also a candidate, I guess, which does mean green Olwen. I hadn't thought of her. Even Lucina with aether is possible.

Breath of Life maybe?

Tiki, Florina, Julia and Felicia?
