User blog:Warlokthegreat/What is my best team option?

So, I want a team that can dish out bb's in no time. I will list my main team and all my other useful units

CURRENT TEAM

(LEADER) Rebel angel Elsel  *5 LV 65 (Breaker)

Diva Hatsune  Miku   *4 LV 55

War Girl Ophilia  *5 LV 47

Dark Tunes Eric *5 LV 47 (Breaker)

Saint Maria *4 LV  60 (max) (Breaker)

and the rest of my units

Ice Keep Copra *4 LV 47 (Lord)

Kajah  *4 LV 12 (Lord)

Goth Kikuri  *4 LV 3

Healer Merith (to replace Maria later) *3 LV 9

And Drakeborn   Lodin   *4 LV 1 (He is new)

So, my question is, which combination of units is the best?

Also, should I use Mimir or Merith?

Note: For some reason, I am lucky enough that almost all of my units are Anima, except the ones who have their types next to them. And, please know I am F2p (Free to Play), and not P2P   (Pay to Play), so my gems are limited.
