If I remember correctly you can only do decent damage to him if you have a fury buff active and there is a synergy with heindal and Angela which gives a fury buff if you dash back and hold block so if you have those characters that is a big helps I did it with a 6 star guillotine 2099
Also you said you have cgr and his special 3 give a temporary fury buff so if you cycle correctly that works I think but if you have heimdal I would recommend the Heimdal synergy if you have him

Use a poison immune champ and use Angela and Hela synergy, I used a 5 star Nimrod when I did it.
