This has happened to me 3 times in a row now. Way past into the infinite streak in the 5 star featured arena.. i use ironman, drax and xxx all 4 star 3/30s and it triggers death squads. Other 4 star 3/30s are fine but when i use ironman drax and someone else so far (3 times) it triggers death squads and screws me over. Can someone please address this issue. Isn't 4 star 3/30s supposed to be enough to maintain the infinite streak??
