I've been thinking on this also. Mainly things that are easy for her to cast and aren't suit dependent.
Taelor- Menace
Bishop- Knock out, study opponent
sue- Shrug off, circle of flames, tread the line
mctavish- shrug off, wrangle critter
Cassandra- breathe fire
Coryphee- Blinding, Orchestral Crescendo
Performer- Expensive gift, seduction
Most of these are ok, some seem good. I like menace and study opponent, especially if study opponent would remain in effect after transforming.
Sue seems godly next to myr as does mctavish.
Coryphee seems good, the pulse damage would be really nice in certain matchups. Coryphee's are also really good by themselves
