So I've been playing with the new null composure fusion rifle and I've been trying to get the new ornaments because I know they're going to be a seasonal challenge eventually. The strike and crucible were easy enough but the gambit one has been a pain. I have played 5 gambit matches in a row and won 4 of them. All rewarding 1% towards the goal besides one game rewarding 2%. I have gotten multiple kills with jotuun/null composure. It says earn bonus by defeating guardians and winning streaks. I have a 4 winning streak and have gotten many guardian kills with jotuun as well as ad multi kills with jotuun. Theres no way I am doing 100 gambit matches in order to get this stupid ornament.
