In my current grand arena, my opponent is running a team of relic 7 Talzin, merrin (omicron) and zombie with all zetas.
I threw a DS mandalorian squad at it (maul and Jango both relic 7 with zetas, and a relic 1 canderous with zeta)
in the beginning, I was able to completely take out Talzin (all times with zombie resurrection) then I was able to take out merrin. But once I killed the zombie all of them revived and killed me. Talzin and merrin were killed by jango. My opponent did not have a datacron on that team. I am not including the opponents name or friend code in case it is a bug and not a potential cheat. Can someone explain it please
