Thracia 776 PMU

Alright, I'm crazy for doing this but here we go. This is gonna be my first playthrough for Thracia since I just finished FE4 not long ago but I have no idea who to use or not so a PMU should make this interesting. I will be following a "newcomers guide" so I'm not going in blind.
Rules:

1. Leif, Finn, and Nanna are free
2. Try not to pick too many troll units. I'm ok with a few, Marty Party inbound but go a little bit easy on me since it's a first playthrough
3. I'm taking 16 units
   Units:
4. Leif
5. Finn
6. Nanna
7. Olwen
8. Marty Party Best Party
9. Conomore
10. Karin
11. Saias
12. Bryton
13. Ronan
14. Asvel
15. Lifis
16. Orsin
17. Homer
18. Salem
19. Dagdar
20. Lara
21. Sara
22. Shiva.
