Loving the update.
Fed my +def=Spd Effie a Brave Lance from my 4* Cordelia. I have a Hinoka and Cordelia at 5* ready to offer as snackrifices, but I am not sure which one to do yet. Coredia's nature is pretty bad for her (+Speed), but she also has the rare Galeforce and I might want to save that for someone else (I do have a Lynn but her nature is unknown so it could be good). Not sure on Hinoka's nature and she's a pretty rare 5* so I wasn't sure to give her up either. Not feeling using 20k to level a Donnel for it either.
Whatever I decide, I'm gonna give her Bonfire and Swap too. Debating on the C slot.
Debating between Marth, Lynn and Erika for my red. Leaning a bit more towards Erika because of Drag Back for Effie and the natural double boosts. She's a -Hp+Attack so she's going to get hit hard by double attacks though, gonna test it out and play around with passive effects.
Also gonna try giving Fae Ardent Sacrifice, Darting Blow and Sol, making her a pseudo healer since she has a strong Renewal and is naturally tanky support without much extra work beyond feeding her a Florina. This can give Effie some more durability without having to run an actual healer and kill my offense.
I'd reall like a solid ranged attacker for the fourth slot (or Ninnian) but nothing's popped yet for me. I have a pretty good Elise I could put in place of psuedo-healer Fae cause loading her up with boosts and Threatens plus the synergy with Effie should make up for the damage loss, but Fae is my only solid Green for the foreseeable future, unless I pull a Nino with a good nature.
That being said, I LOVE being able to play around with weird/unorthodox combos based on what i get. Just about every unit has a place now, and just about all of your favs can be used in a team and be better than before if you pull them. Delightful.
