I completed the dragon 20 and also ice golem 20. As of right now, I am farming ice golem 20 to get the artifacts. I believe it is time for me to go for fire knight 20 in the coming future. 

As of right now, I am using Miscreated monster, Kael, Procecutor, Apothecary and Armiger for stage 17 of fire knight.

I want your help on the team compostion.

recently, I got Morag and coldheart. I want to put both of them in Fire knight 20. I am willing sacrifise Kael but other 4 are vital. Miscreated monster for stun and sheild, Armiger for turnmeter, Procecutor for Heal reduction , speed and multiple hits and apothecary for heals and speed. 

I wanted to add Morag for allly attack and Coldheart for 4 hitters on A1

So, I don't know what should I be doing right now. 

Can anyone suggest me on which team I should use?
