Need Armor Team Help.

I pulled a Halloween Kagero and I’m really happy. She is +ATK, -HP which isn’t too bad I’m guessing since refinement and all that but I was wondering who to replace on my armor team. My team is:

- Black Knight (want to replace him with Winter Tharja when I hopefully get her ;-; )
- Effie +5 (+RES, -SPD) has Berkuts Lance or I can go with +ATK -SPD
- Hector (Neutral)
- Halloween Henry (+ATK, -HP)

Also have H!Dorcas as an option for green as well so... yeah I like him and he’s an option if that changes anything, and I still have the free Takumi for close counter if that helps Kagero’s case.
Any advice would be appreciated and I hope all of you have the best of luck getting who you want with good ivs!
