Rate my Infantry Awakening Team

I'm Awakening scum, and I am also so unlucky that I have had to promote my units to 5 star heroes because I have not gotten any by spending over 120 orbs from the Christmas banner. However, I did manage to Robin F as seen in the picture below, and I wanted to make a team * that is based around her with the units I have:

Robin: See Image

Chrom: Brave Sword +, Death Blow, Reciprocal Aid, Desperation/Brash Assault build. Atk+ Res-

Nowi: Lightning Breath (Def), Reposition, Steady Breath, QR, Threaten Res, Close Counter 3 Seal.

Olivia: 4 star 10+ Merge: Armorsmasher +, Triangle Adept, Wings of Mercy, Hone Atk 3, Spur Atk 3 seal, Luna

*Note that this is for fun.
