Aversa is the best thing that happened to F2P Flier emblem.

Why?

1. Flier mages are all 5* exclusive, meaning hard to merge and find optimal IVs.

2. Red fliers are scarce and the best ones are rare (Elincia and Flying Ryoma)

3. Having a +2 Aversa is already a nice plus to a flier team.

4. If Aversa has at least a good offensive statline as compared to H!Nowi or S!Tana even without access to IVs, she can run a Bladetome set just as good as the two.
