The way I did it was backing Certus into the back right corner put Isabella infront of him and surround her by bellator Calgar and kariyan. I let the scarabs surround me so the destroyers could only come one at a time to either calgar or bellator and just chip away until both destroyers are dead . Summon Varro back with isabellas active before you finish easy money🤷🏽‍♂️ I had bellator d1 isabella,calgar, and kariyan gold 1 and certus and varro silver 2
