Help in 5.4.6 (Ultron Boss)

Negativity_1

I need help, this is the fight I am stuck on. I don't have red mags, no Loki and no wiccan at 4 or even 5 stars.
I tried to harvest damage with galan, but he just evades so frequently and combos me and I die, I've lost over 13 revives and 25 health potions. Please any tips will help
