F2P Flier Emblem red unit?

I'd work on that +Atk/-Def Caeda. Defense is not her best stat, so you can easily take a loss in it. Caeda needs all the attack she can get, so having extra attack will help her, on top of it being her superboon. Also, if you have the feathers, make her five star so you can give her the Wing Sword. Having a flier that's effective against cavalry and armored will be really helpful.

Michalis and Shigure would be good flier units to start working on also. You should be able to have some decent fliers to work with until you start pulling some more fliers to either use as merge projects or advance a flier team further with.

Palla is better, shes the best red flier that isn't summer young tiki, here's a picture of mine ignoring the weapon triangle.

I personally like Caeda more due to her prf and her stat line. Also Palla is very useful as fodder for goad flier. I would merge Caeda (if this is just a regular flier team you could probably just test them both out)

Caeda, i like her weapon with effective damage and her res stat is usefull for ploys.

Caeda may have better speed and a Prf eapon, but Palla is more well rounded. Palla can easily run Fury to make herself bulky

Overall, from a statistical standpoint, Caeda wins due to having a Prf.

They both have their advantages, but I won’t speak for Palla since I haven’t invested into her. Don’t listen to the comments about Caeda not being able to do damage. I have Caeda at 5*+10, and she has been phenomenal in my flier emblem team. With Swift Sparrow and a Hone fliers buff, she has 59 Atk and 51 Spd. Ontop of that, in tier 20/21 you face armor 95% of the time and her prf weapon destroys them. Run Def Ploy for her seal and basically add 5 more Atk. She’s a great choice for a “F2P” red flier

Caeda for sure.
