User blog:Zestirio/Could I get suggestions on making a good party for GQ/Quest/Raid?

[This is my first blog post, so sorry if I didn't make it right ;-;] Ok, so I'm currently level 89. The units that I have are:

(7*) (Lord) Shadow Assailant Kuda - Max Level, BB and SBB only.

(7*) (Breaker) Ardent Dawn Avant - Max Level, BB only.

(7*) (Anima) Glamorous Peril Savia - Max Level, BB, SBB, and UBB unlocked.

(7*) (Breaker) Steel Automaton Voldoga - Level 110, BB, SBB, and UBB unlocked.

(7*) (Guardian) Double Voltage Julius - Level 102, BB, SBB, and UBB unlocked.

(6*) (Anima) Holy Earth Lance - Max Level, BB only.

(6*) (Breaker) Hades Stun Radia - Max Level, BB only.

(5*) (Guardian) Chieftain Avani - Max Level.

(5*) (Guardian) Noble Cavalier Krantz - Max Level.

(5*) (Breaker) Beryl Edge Quaid - Max Level.

I would like to create a team that specializes in sparks or criticals, or a team that can hold it's own in a GQ or Raid Battle. I'd really appreciate some help on this matter. I have all of the Six Heroes spheres as well, if that helps.
