Rate my team

I think last week I posted that finally I pulled my second axe armor unit, hard to believe because I have been playing since the release day. So I tried to build one of those famous armor emblems team, because I wanted to make one for long time ago and finally I almost completed mine. (Need help with Sheena a) slot, and also I'm thinking about give vantage to my Effie and change Carrot Lance + for Berkuts Lance +, but I need to save a lot of feathers). I will show my unit team now at some pictures. Those are they IVs: Effie (+Def/-Spd) Gwendolyn (-Def,+Res) (Waiting for a +Def/-Spd or +Res/-Spd), Sheena (+Def,-Res) (The same as Gwendolyn), Black Knight (Neutral). Any opinions?
