He’s much easier after the recent nerf to act 6
The best encouragement I can offer you is this...
You will forever be better than pixiecocoa for even attempting the fight.
If you have a Juggernaut, use him. He's really not as hard as you think, you'll get it. Worse case scenario, you spend some revives.
My one piece of advice is, if you get frustrated, I know I did, put your phone down & do something else for a while. Pick it back up later. Nothing worse than angry, flustered mcoc gameplay
I plan to use 6* rank 4 sig 200 ascended Mr Sinister for the reverse controls bit and I have over 900 free cavalier and Thrownbreaker crystals if I need revives so should be ok.
I've got from 6.2.6 to Grandmaster without a single revive.
I see he's "only" got 7.5m health where used to have almost 10m
You get 10 blunders before he kills you with an sp3 now
