Other than people you're forced to bring, I use Zihark, Stefan, Haar, Nephenee, Tibarn, Geoffrey, Pelleas, Ilyana, Soren, Rolf, and Rhys. I think that was everyone, it might be too many, but these are who I use.

Eww, laguz kings.

My team:
-Haar
-Oliver
-Bastian
-Renning
-Tanith
-Sigrun
-Elincia
-Heather
-Kieran
-Danved

You know, I really hate how Micaiah gets to 3rd tier promote, AT the final chapter. Her and Sothe are really hard to level up because of that.

Micaiah isn't worth anything but another healer in the final chapter.

I used:

-All required (Ike+)
-Nephenee+
-Soren
-Haar
-Jill
-Nolan
-Edward
-Shinon+
-Gatrie
-Elincia

+ denotes Nihil. I missed a Nihil so <_<

Those are all pretty good in my opinion. I've actually never used Jill so much, because Haar is so much better, and I like diversity in my team. I also never leveled her up much in Micaiah's story, cause I was too busy working on Micaiah, Sothe, and Zihark. Edward is actually really good, i usually use him a lot, just not in the final battles, same with Nolan.

Jill is amazing in Part 3.

I didn't like Edward after Part 1 ironically XD

In my last Hard Mode run

Aran
Laura
Leonardo
Meg
Volug
Titania
Tormod
Soren
Ilyana
Rafiel

I later left out Sothe and Ilyana to bring along Gareth and Nasir to the last two missions. I've seen Gareth do a lot of OHKOs on those spirits (because of Parity) which all flocked to Ena in the middle who maxed out Resistance.

I plan to test a new trick with Vika. Skills to her are Savior, Resolve and Tear. She'll support either Volug or Zihark (must be an Earth affin). I don't really have to raise him, she'll be Rescuing them for the etire mission through and take the support bonuses without needing to protect him. Savior removes the penalties and Resolve would really make her untouchable to an absolute if something drops her HP to half.
