Need help.

Alphonse. Low speed makes him unplayable under normal circumstances. Switching to BraveSword, Fury, Desperation should work. Distant counter justifies keeping his weapon. vantage would then work better.

Ana. Fury, Desperation. ThreatenSpd or HoneSpd. Ana should run it since her base speed is the highest and so she needs it the least. Team buffs like this might help prevent alphonse from getting shot down like the dog he is

Sharena. actually pretty top tier already. change to fury/desperation for some more bigdick dmg.

4th slot is the season unit to double arena score. having Fury3 on three units raises team BST by 36, and these three units surprisingly already had decent base values.

Not a silly dream with skill inheritance.

If you're really invested and want to make the best character possible, I would recommend the following.

No advice for Al, he's a baddie

Anna: Utility damage dealer that gives buffs
-Armads
- Death Blow (A)
- Renewal (B)
- Hone Atk (C)

I personally like Alfonse, he's not a bad unit like most people make him out to be.
I think swordbreaker might be nice on him as he then can out damage and duel other sword users, potentially letting him one round them

I think Alfonso will be very useful with brave sword, vantage/close counter and aether(from Chrom)/sol. His high pH, def and not-too-bad res can keep him alive for one turn with rangers clean the area. However, untilless Nintendo gives a way to develop stats of these three initial characters, they would be left behind because they can't merge ally. I have a friend on this game that owns a +10 Merric, I was able to use him during voting gauntlet, he was magnificent.
