Camilla lead, James, Shiva, Yvette, Kal.
Focus on Camilla, shes a great melee lead.
Yvette and Kal can be on defense also.
No one likes Kal but he is good, comes with an impair weapon, he is neutralize and all around going to help stop the enemy from rushing.
Yvette has heal, bonus hp and focus for 3 turns to only 3 but this will allow you to bypass shields and no be confused or taunted and also heal you team so you can stay in the fight.
Shiva is amazing and i love her bleed, if you get Rick from the leagues store you can use both him and Shiva and make a nice bleed team.
James is really hitting like a beast, replace his weapon with stun, give him some crit and he will kill yellows easy.
For defense you can do Duane lead, Yvette, Kal, Carley, and maybe that Zeke since he is gaurdian and will have crit from Duane but i would just use James or Shiva
