Completed this triumph by hitting top 10% in this past Guardian Games, was expecting the emblem to be sent in game but was told that it's redeemable in bungie rewards, so I checked regularly for over a week and it still hasn't been available to claim for me. It's supposedly supposed to expire at 11am July 7th, which is in an hour at the time of posting so I'm really running out of options. Hopefully it'll be distributed for people who couldn't get it like me :/
