Apoc 2, No Praetus and no Ingrid, 120k or HIGHER!

Phase 1: Save Ferssi ult for slams and laser damage. Save Wukong ult for Semrah's saw skill. Minimum A3 Wukong to maximize stuns. Use all dps ults and constance ult when you can and Kigiri's ult when he is about to be hit. 4th rotation and onward, use Carnelians ult right as the saw leaves the screen. That way she refreshes her unyielding stacks on all units.

Phase 2:  Save Ferssi ult for slams and Earth Shatter. Kigiri will dispel Semrah's defense buffs. 4th rotation and onward, time Carnelian ult with attacks. For the slam, use Carnelian ult as soon as his right hand moves (your left while looking at the fight). For the Earth Shatter skill, use carnelian ult when Semrah visibly glows. Use dps ults and constance ult when up and Kigiri's when he is about to be hit.

Phase 3: This will be a tough phase if your Elowyn has LESS THAN 100% rage regen (excluding Pantheon bonus). Try to time it so all dps ults + constance ult is availabe for the start of the fight. Activate as soon as the phase begins. Wait for the first Acidic Venom. Semrah will raise his arm before applying venom. At the height of his arm raise, use Elowyn ult. You will know its done correctly if you cleanse all the poison as soon as it is applied. On the second cast of Acidic Venom, Carnelian ult will be used. Wait for the poison to drop your team under 50% Hp then use her ult. During 4th rotation and onward, use her ult when your unit's hp is at 70-60% hp. Continue to use dps ults and constance ult. Once again, use Kigiri's ult right before he is hit. SPECIAL NOTE: Do not use Kigiri's ult before Acidic Venom. If you do, he wont be cleansed by Elowyn and will drop quickly.

STATS TO AIM FOR AND MORE TIPS:

Tank needs highest HP, goal: 100k
ALL OTHER UNITS NEED 30k hp MINIMUM

DPS units need minimum 16k attack, goal: 20k attack with 300%+ cdmg

Elowyn absolutely needs 100%+ rage regen (without Pantheon bonus) UNLESS you're using 2 cleansers. Then you can just alternate cleansing each attack rotation during Phase 3. SPECIAL NOTE: Elowyn's cleanse range is increased during her ult, so all your units do not need to be in her range of healing. Midan is not the same. She only cleanses in her healing range, same for Nissandei and other cleansers.

Carnelian ult needs to be maxed for the best efficiency. She also needs at least 600 attack speed to properly apply her Soul Essence quickly. 
If you're not using Carnelian, you will need double cleansers during 4th rotation and onward.

Torodor WILL NOT STUN in his position. For him to be able to stun he needs to be touching Semrah.

Use Elowyn's wood elf in emergency situations. Especially during Phase 3. It will help keep Laya and Torodor alive. Wukong's clones wont allow you to be able to place them next to him.

Cycle Laya's ult as much as possible. The only exception is if you have everyone's ult available. Wait to use her ult AFTER everyone's ult is cast in this case. SPECIAL NOTE: Phase 3, only use Laya ult after Elowyn ult, to build Elowyn's ult quickly.

Focus on survivability first and dps second. Can't deal damage if you can't survive the attacks.

REPLACEMENTS FOR UNITS:

I understand my teams are not f2p friendly. That being said most units can be replaced with more f2p friendly units.
Lucius can replace Kigiri for dispel, but dps will not be comparable. Wukong's damage cannot be replaced, but Helga can stun more than he can. Twyla can be replaced by Arrogance or Lust. Epics can be used in replacement of Lords, but I don't see it going further than 80k. Epic unit dps is just not there and base stats are low. Carnelian can be replaced with a 2nd cleanser.

Non-negotiable : 
Elowyn. She is an absolute must for going higher than 80k. A combination of Midan, Nissandei, or Dassomi can help. Cleansing rotation will need to have special attention paid to. 1 mistake and you're done. 

Constance. Dolores will not be able to survive in later rotations without sacrificing attack for hp. Even then, those slams will wipe her.
